hey, how would i go about converting a char* character array to a double.
I would like to create a function that takes a char array as a parameter such as "1234.1" and then return that as a double value 1234.1.
Is there a function that would allow me to do this or would i have to go about programming it myself?
Thanks.

Provided the array is actually a string with a terminating '\0' character at the end, you can use strtod. Or, since this is C++, stringstreams make the conversion intuitive if you're used to cin and cout:
#include <sstream>
double to_double ( const char *p )
{
std::stringstream ss ( p );
double result = 0;
ss>> result;
return result;
