FormulaJS

This is an interpreter for basic formulas, based on an original idea by @tsalmon.

Note: this is an old, unmaintained project.

Usage

formula <file>
formula <formula>

Features

• Floats & integers, negative and positive numbers
• basic operations (+, -, /, *) and power (^)
• constants (E, PI)
• some syntaxic sugar (e.g. (…)(…) instead of (…)*(…)), various alternatives for some operations (e.g. ⋅ or × instead of *, ÷ instead of /).

Examples

formula -2+3                 # 1
formula "((42-5)(12*3+2))^3" # 2779431416
formula PI*1.5               # 4.71238898038469
