Allow trailing spaces on strings for conversions

[phlptp]

Allow trailing spaces on strings for conversions to floating point and integers.

There was a potential confusing error that could occur if strings with trailing spaces were converted to integer or floating point values. This PR allows trailing spaces in the strings that would otherwise be convertible to the appropriate numerical type.

Fixes #1094
