EvalMath - safely evaluate math expressions
DESCRIPTION
Use the EvalMath class when you want to evaluate mathematical expressions
from untrusted sources. You can define your own variables and functions,
which are stored in the object. Try it, it's fun!
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 = $m->evaluate('3*f(42,a)');`
METHODS
`$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.
`$m->funcs()`
Returns an array of all user-defined functions.
PARAMETERS
`$m->suppress_errors`
Set to true to turn off warnings when evaluating expressions
`$m->last_error`
If the last evaluation failed, contains a string describing the error.
(Useful when suppress_errors is on).
