Install.txt
—————-
Here is a detailed description of the solution, sources, necessary tools, and ways, how the sm_calculator (SM Calculator) solution 0.1.0.2 can be built and tested:
Install.txt.

Third-party libraries and tools
—————-
You can find a suite of third-party libraries and tools here (SM Calculator – 0.1.0.2): cmocka, getopt, safestringlib, win_flex_bison (Install.txt). Here are:

  • win_flex_bison – windows port of Flex and Bison tools
  • getopt – library (adopted for Visual Studio) for parsing of command-line aruments
  • safestringlib – a multi-platform library, that contains API for safe control of memory and strings
  • cmocka – unit test library

You can download win_flex_bison for assembling the sm_calculator (SM Calculator) solution 0.1.0.2 on Windows and you don’t need other third-party libraries for assembling the sm_calculator (SM Calculator) solution 0.1.0.2 as they are already included in sources (/deps).

Tools necessary for assembling of the project:
—————-

Windows platform:

  • Visual Studio 2019 (including NMake tool);
  • CMake;
  • flex;
  • bison;
  • diff (optionally);
  • Python 3 (optionally);

Linux platform:

  • GCC;
  • Make tool;
  • CMake;
  • flex;
  • bison;
  • bash;
  • diff (optionally);
  • Python 3 (optionally);

Some issue of assembling on the Linux platform, using synchronized log (definition: SM_SYNC_LOG):
—————-

The sm_calculator (SM Calculator) solution 0.1.0.2 contains project log_lib, which contains the support of synchronized print (definition: SM_SYNC_LOG). As a rule, there is no necessity of usage of synchronizing print, as every log print is executed by one call of runtime the function fprintf  of synchronized C-runtime API. But there are some cases when this synchronizing can de used (Install.txt). Windows tree of sources uses standard critical section objects in synchronizing API. Linux tree of sources uses thread API, defined by C11 (ISO/IEC 9899:2011) standard, using #include <threads.h>. But not all packages of GCC contain the support of the thread API, defined by C11 (threads.h), though GCC supports the C11 standard. This problem can be resolved after updating of usage of the thread API, defined by C11 (#include <threads.h>) to the usage of the POSIX thread API (#include <pthread.h>).

Base syntax of functions:
—————-
function (arg1[,arg2])[;]

Base syntax of operators:
—————-
arg1 operator arg1[;]
operator arg[;]

Operator assign (‘=’) can be used only in commands (f_precision, i_format, a_unit).

Types of values:
—————-

  • Integer data (long long type – 64 bits);
  • Float data (long double type – 64 bits);
  • Strings (max length of string 1021 ASCII symbols);

Integer data:
—————-
Length of Integer data – 64 bits (including sign), i.e.
max integer value == 2^63-1;
min integer value == -(2^63-1);
Integer value can be entered and output in follow formats:

  • decimal (‘dec‘);
  • octal (‘oct‘);
  • hexadecimal (‘hex‘);
  • binary (‘bin‘);

The output format of integer value can be defined by command:
i_format = <dec|hex|oct|bin>[;]
A user can use shorter way for defining of the output format of an integer value, using commands:
dec[;]
hex[;]
oct[;]
bin[;]

The input format of an integer is defined by following rules:

  • if a user enters integer value in octal format, he should use as least one lead ‘0’ symbol (for example: ‘0712377’, ‘-0712377’);
  • if user enters integer value in hexadecimal format, he should use as lead ‘0x’ symbols (for example: ‘0x394ff’, ‘0xfffffffffffc6b01’);
  • if user enters integer value in binary format, he should use as lead ‘b’ symbol (for example:  ‘b00111001010011111111’‘b1111111111111111111111111111111111111111111111000110101100000001’);
  • if user enters integer value in decimal format, he shouldn’t use any additional symbols (for example: ‘129077’‘-129077’);

A user should take into account, that size of integer value is 64 bits (including sign), during entering value in various formats;

A user can enter negative values (in octal and hexadecimal) using as sign ‘-‘
as two’s complement format (see examples in the file ReadMe.txt):
-0712377 (oct) or 01777777777777777065401 (oct) == -234751 (dec)
-0x394ff (hex) or 0xfffffffffffc6b01 (hex) == -234751 (dec)

If user need to get current output format of integer values, he needs to use command:
i_format[;]

SM Calculator tool supports the suite of functions, which provide converting of various formats of integer values, whatever defined current output format of integer values:
dec2oct dec2hex dec2bin oct2dec hex2dec bin2dec.

Float data (long double – 64 bits):
—————-
The output format of float values always defined in decimal format. User can tune the precision of float value output, using the command:
f_precision = N[;]
, where N = [0,20]|exp, i.e. maximum precision of output of float value is ’20’.

Also, N can be defined as ‘exp’. In this case, the float value will be printed in an exponential format.

The input format of float values always defined in decimal format. A user can enter values as in floating form format as in exponential format.

If a user needs to get current output current precision of float, he needs to use the command:
f_precision[;].

Strings:
—————-
User should enter string value, using the following format:
"string_value" | 'string_value'.
Max length of the string – 1023 ASCII symbols with quotes(‘ or “)
or 1021 ASCII symbols without quotes(‘ or “).

String values aren’t used during calculations but could be used for the formatting of outputs in file processing, using the function
echo.

Default angle unit configuration:
—————-
SM calculator supports some suite of trigonometrical functions:
sin cos tan asin acos atan.
Also, SM calculator supports follow units for measuring of angles:

  • radians (‘rad‘)
  • degrees(‘deg‘)
  • gradians(‘grad‘)

SM Calculator tool contains the current configuration of the unit for measuring of angles. This parameter defines, which unit for measuring of angles will be used by trigonometric functions, i.e. if the current configuration of the unit for measuring of angles is radians, a user should use radians as parameters of trigonometric functions: sin(3.1415926536) or sin(pi), cos(1.5707963268) or cos(pi/2.0), if the current configuration of the unit for measuring of angles is degrees, a user should use degrees as parameters of trigonometric functions: sin(180.0), cos(90), same issue with the usage of gradians.
The current configuration of the unit for measuring of angles can be defined by the following command:
a_unit=<deg|rad|grad>[;]

Also use can setup current configuration of the unit for measuring of angles, just using following commands:
deg[;]
rad[;]
grad[;]

User can get current configuration of the unit for measuring of angles using the command:
a_unit[;]

SM Calculator tool supports the suite of functions, which provide converting of the various unit for measuring of angles, whatever defined current configuration of the unit for measuring:

grad2rad rad2grad rad2deg deg2rad grad2deg deg2grad

Current configuration:
—————-
A user always can get current configuration, using the command:
config[;]
The result of the command config[;]:
Current Configuration :
---------------------------------------------
Current double precision : EXPONENTIAL;
Current output format of integers : dec;
Unit of measurement of an angle : rad;

Constants:
—————-
SM Calculator supports follow float (64 bits) constants:
pi
exp
gamma
phi

Constants return float values. They can be used in expressions as arguments of functions and operators.

Examples:
—————-

Base syntax of commands:
—————-
command[;]
command=arg[;]

Base syntax of functions:
—————-
function (arg1[,arg2])[;]

Base syntax of operators:
—————-
arg1 operator arg1[;]
operator arg[;]

Operator assign (‘=’) can be used only in commands (f_precision, i_format, a_unit).

Types of values:
—————-

  • Integer data (long long type – 64 bits);
  • Float data (long double type – 64 bits);
  • Strings (max length of string 1021 ASCII symbols);

Integer data:
—————-
Length of Integer data – 64 bits (including sign), i.e.
max integer value == 2^63-1;
min integer value == -(2^63-1);
Integer value can be entered and output in follow formats:

  • decimal (‘dec‘);
  • octal (‘oct‘);
  • hexadecimal (‘hex‘);
  • binary (‘bin‘);

The output format of integer value can be defined by command:
i_format = <dec|hex|oct|bin>[;]
A user can use shorter way for defining of the output format of an integer value, using commands:
dec[;]
hex[;]
oct[;]
bin[;]

The input format of an integer is defined by following rules:

  • if a user enters integer value in octal format, he should use as least one lead ‘0’ symbol (for example: ‘0712377’, ‘-0712377’);
  • if user enters integer value in hexadecimal format, he should use as lead ‘0x’ symbols (for example: ‘0x394ff’, ‘0xfffffffffffc6b01’);
  • if user enters integer value in binary format, he should use as lead ‘b’ symbol (for example:  ‘b00111001010011111111’‘b1111111111111111111111111111111111111111111111000110101100000001’);
  • if user enters integer value in decimal format, he shouldn’t use any additional symbols (for example: ‘129077’‘-129077’);

A user should take into account, that size of integer value is 64 bits (including sign), during entering value in various formats;

A user can enter negative values (in octal and hexadecimal) using as sign ‘-‘
as two’s complement format (see examples in the file ReadMe.txt):
-0712377 (oct) or 01777777777777777065401 (oct) == -234751 (dec)
-0x394ff (hex) or 0xfffffffffffc6b01 (hex) == -234751 (dec)

If user need to get current output format of integer values, he needs to use command:
i_format[;]

SM Calculator tool supports the suite of functions, which provide converting of various formats of integer values, whatever defined current output format of integer values:
dec2oct dec2hex dec2bin oct2dec hex2dec bin2dec.

Float data (long double – 64 bits):
—————-
The output format of float values always defined in decimal format. User can tune the precision of float value output, using the command:
f_precision = N[;]
, where N = [0,20]|exp, i.e. maximum precision of output of float value is ’20’.

Also, N can be defined as ‘exp’. In this case, the float value will be printed in an exponential format.

The input format of float values always defined in decimal format. A user can enter values as in floating form format as in exponential format.

If a user needs to get current output current precision of float, he needs to use the command:
f_precision[;].

Strings:
—————-
User should enter string value, using the following format:
"string_value" | 'string_value'.
Max length of the string – 1023 ASCII symbols with quotes(‘ or “)
or 1021 ASCII symbols without quotes(‘ or “).

String values aren’t used during calculations but could be used for the formatting of outputs in file processing, using the function
echo.

Default angle unit configuration:
—————-
SM calculator supports some suite of trigonometrical functions:
sin cos tan asin acos atan.
Also, SM calculator supports follow units for measuring of angles:

  • radians (‘rad‘)
  • degrees(‘deg‘)
  • gradians(‘grad‘)

SM Calculator tool contains the current configuration of the unit for measuring of angles. This parameter defines, which unit for measuring of angles will be used by trigonometric functions, i.e. if the current configuration of the unit for measuring of angles is radians, a user should use radians as parameters of trigonometric functions: sin(3.1415926536) or sin(pi), cos(1.5707963268) or cos(pi/2.0), if the current configuration of the unit for measuring of angles is degrees, a user should use degrees as parameters of trigonometric functions: sin(180.0), cos(90), same issue with the usage of gradians.
The current configuration of the unit for measuring of angles can be defined by the following command:
a_unit=<deg|rad|grad>[;]

Also use can setup current configuration of the unit for measuring of angles, just using following commands:
deg[;]
rad[;]
grad[;]

User can get current configuration of the unit for measuring of angles using the command:
a_unit[;]

SM Calculator tool supports the suite of functions, which provide converting of the various unit for measuring of angles, whatever defined current configuration of the unit for measuring:

grad2rad rad2grad rad2deg deg2rad grad2deg deg2grad

Current configuration:
—————-
A user always can get current configuration, using the command:
config[;]
The result of the command config[;]:
Current Configuration :
---------------------------------------------
Current double precision : EXPONENTIAL;
Current output format of integers : dec;
Unit of measurement of an angle : rad;

Constants:
—————-
SM Calculator supports follow float (64 bits) constants:
pi
exp
gamma
phi

Constants return float values. They can be used in expressions as arguments of functions and operators.
