PerlCalc is a small command-line calculator tool often implemented in or inspired by Perl that provides quick arithmetic, numeric functions, and scripting-friendly expression evaluation. Typical features and uses:
- Basic arithmetic: +, -, *, /, parentheses for grouping.
- Floating-point and integer support, with configurable precision.
- Built-in math functions: sin, cos, tan, exp, log, sqrt, pow, etc.
- Variable assignment and simple scripting for repetitive calculations.
- Command-line friendliness: read expressions from arguments, standard input, or files; useful in shell scripts.
- Extensibility: can load or define custom functions and constants (depending on implementation).
- Useful for developers, sysadmins, and anyone needing quick calculations in terminal workflows.
Example usage (conceptual):
- perlcalc ‘2+2’
- perlcalc ‘sin(3.⁄2)’
- perlcalc ‘x=5; x3’
