< Template:Str number

Template documentation[view] [edit] [history] [purge]

This template uses Lua:

Module:String (sandbox)

The Template:Str number/trim extracts a number at the start of parameter 1.

It takes a string as parameter, and returns the string trimmed to the beginning number if non-numeric text does not appear before the first number.
