C++ IsFloat function

Question

Does anybody know of a convenient means of determining if a string value \"qualifies\" as a floating-point number?

bool IsFloat( string MyString )
{
   ... e

This is a common question on SO. Look at this question for suggestions (that question discusses string->int, but the approaches are the same).

Note: to know if the string can be converted, you basically have to do the conversion to check for things like over/underflow.
