You can define your own variables and functions, which are stored in the object. Try it, it's fun! ``` SYNOPSIS -------- [](#synopsis) ``` `$m = new EvalMath;` `// basic evaluation:` `$result = $m->evaluate('2+2');` `// supports: order of operation; parentheses; negation; built-in functions` `$result = $m->evaluate('-8(5/2)^2*(1-sqrt(4))-8');` `// create your own variables` `$m->evaluate('a = e^(ln(pi))');` `// or functions` `$m->evaluate('f(x,y) = x^2 + y^2 - 2x*y + 1');` `// and then use them` `$result = $m->evaluate('3*f(42,a)');` `// use methods (calc functions) `$m->evaluate('1+max(2,3)') // => 4` `$m->evaluate('if(1=2, 2+2, 5+5') // => 10 ``` METHODS ------- [](#methods) ``` `$m->evaluate($expr)` Evaluates the expression and returns the result. If an error occurs, prints a warning and returns false. If $expr is a function assignment, returns true on success. `$m->e($expr)` A synonym for $m->evaluate(). `$m->vars()` Returns an associative array of all user-defined variables and values. `$m->funcs()` Returns an array of all user-defined functions. ``` CALC METHODS (CALC FUNCTIONS) ----------------------------- [](#calc-methods-calc-functions) - `max(n...,m)` returns one of given arguments with maximal value - `min(n...,m)` returns one of given arguments with minimal value - `if(expr, true_value, false_value)` (has a `iif` synonym) returns `true_value` of `false_value` depends of `expr` evaluation result CREATE YOUR OWN CUSTOM CALC METHODS (CALC FUNCTIONS) ---------------------------------------------------- [](#create-your-own-custom-calc-methods-calc-functions) ``` You can create custom classes, that implements custom calc methods. ``` TODO ---- [](#todo) - Improve documentation - Ability to add custom operators - More tests CREDITS AND COPYRIGHTS ---------------------- [](#credits-and-copyrights) This software integrates several libraries and patches by: - Original EvalMath library, (C) 2005 Miles Kaufmann - Modifications for 'calc functions' by Moodle, - Composer/Packagist version, (C) Daniel Bojdo, ### Health Score 33 — LowBetter than 72% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity13 Limited adoption so far Community11 Small or concentrated contributor base Maturity75 Established project with proven stability Bus Factor1 Top contributor holds 85.5% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
