Simple casting question

[gmgarrison]

I've got a numerical value stored in a CString that I'd like to have in a double. What's the most accurate way of casting? Thanks in advance...

Depending on your context and needs either one of the following might provide a solution, however there are others like scanf().

Hope this helps

strtod, wcstod
Convert strings to a double-precision value.

double strtod( const char *nptr, char **endptr );

double wcstod( const wchar_t *nptr, wchar_t **endptr );

Each of these functions converts the input string nptr to a double.


atof, atoi, _atoi64, atol
Convert strings to double (atof), integer (atoi, _atoi64), or long (atol).

double atof( const char *string );

int atoi( const char *string );

__int64 _atoi64( const char *string );

long atol( const char *string );
