The function to convert a char * to a float is atof, with its only argument a char * and it returns a value of type float. It is found in in the stdlib.h header file. So you would use it like this:

#include <iostream>
#include <stdlib>
using namespace std;

int main()
{
        char asdfString[5] = "54.2";
        float asdfFloat;

        asdfFloat = atof(asdfString);

        return 0;
}

...and Voila, you can then use asdfFloat in calculations. The atoi function is exactly the same as the atof function, but it returns an integer value instead.
