Use[edit]
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

2+(3*4)-5
