- processing of command-line expression(s);
- interactive mode (user enters expression(s), using standard input device/console).
A user can use the same expressions in all these modes (processing of the file,
processing of command-line expression(s), interactive mode). I.e. SM Calculator tool supports the same lexemes and grammar rules in all modes.
Please, read ReadMe.txt for more info about launching the SM Calculator tool in modes of execution.
Limitations/disadvantages of the sm_calculator (SM Calculator) tool 0.1.1.3:
—————-
- sm_calculator (SM Calculator) tool 0.1.1.3 writes full log with detailed info without filtering of log messages by log level and without rolling of log files; So, a user should control the length of the log file by himself;
- sm_calculator (SM Calculator) tool 0.1.1.3 doesn’t guarantee correct execution when a user uses Unicode (UTF-16, partially UTF-8) encoding; sm_calculator (SM Calculator) tool 0.1.1.3 has been tested, for the usage of US-ASCII encoding symbols; Possible (according to cursory testing) user can use UTF-8 encoding (including national symbols) on Linux platform;

Base syntax of functions:
—————-

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, user 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:
—————-
