You must write the code to evaluate into the <eval> and </eval> tags. So far only it supports the following functions, but extensions are anticipated.

Code	Description
#+#	Adds the numbers.
#-#	.
#*#	.
#/#
(...)
#.#	Decimal point.
#e#	Scientific notation (only positives).
{{Template}}	Process the template or variable and replaces it with the returned value. Example: {{CURRENTYEAR}}
{{{Parameter}}}	Process the parameter and replaces it with the returned value. Example: {{{1|0}}}.

NOTE: This parser does the operations beginning at the left. Here are a few examples:

2+3*4-5 2+3*4-5 5*4-5 20-5 15

2+(3*4)-5 2+(3*4)-5 2+ 12 -5 2+ 12 -5 14-5 9
