Version 1.1
DISCLAIMER. This plugin uses php eval()
to evaluate the math string you provide. The following check is performed prior to the eval()
method being called. This should ensure that only numeric and numeric operators are present in the string. Note that trig functions currently are not supported because of this preg_match call. If you can improve my checking method please feel free to drop me an email and let me know and take a stab at it yourself. I claim no responsibility for this plugin.
if (!preg_match("/^[^a-zA-Z\!\@\#\$\%\&\{\}\[\]\?\>\<\,\"\:\;\~\'\`]+$/", $match)) { $renderer->doc .= '{{mathop>}} ERROR - Not A Valid Entry, only numeric and operators are allowed'; return true; }

Description
This plugin reads in a string of math operations and renderers the result of the operations. Any math operation should be valid as the plugin makes use of PHP eval() on the entered string. Note: Trig functions will not work in version 1.1 due to the way the string is checked for malicious code.
Syntax
{{mathop>[math_string]&[round_number]}}
math_string
contains the string to be evaluated (ex. 2 + 4 * 10 / 34)round_number
is optional, it is the number of digits display on the right side of the decimal point. Setting this will round off to the specified precision.
