istring crop_numeric

(

const istring &

input

)

Eats the numeric characters from the front of "input".

This and crop_non_numeric() return a string that is constructed from "input" by chopping the numerical (or non-numerical) characters off of the beginning. The types of numbers supported are floating point, but it will generally work for integers also (problems arise when mixing in the period, e, E, +, and - characters with integer numbers).
