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).

| bool is_floating_point | ( | numeric_type | t | ) |
returns true if the specified numeric_type is a floating_point type.
this is useful in templates where one wants to know about the templated type.

Guesses the formatting string needed for the type provided.
Returns a string that is appropriate as the format specifier of a printf (or the istring constructor) given the template type. templates can rely on this to print numerical types correctly.
