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.
