From wxString methods, this one looks like our friend. Edwin, is it available
in wx2.8 ?
Conversion to numbers
The string provides functions for conversion to signed and unsigned integer and
floating point numbers.
All functions take a pointer to the variable to put the numeric value in and
return true if the entire string could be converted to a number. Notice if
there is a valid number in the beginning of the string, it is returned in the
output parameter even if the function returns false because there is more text
following it.
bool ToDouble (double *val) const
Attempts to convert the string to a floating point number.
bool ToCDouble (double *val) const
<-----------
Variant of ToDouble() always working in "C" locale.
