you know how sprintf(numbers, " %0.17f", somenumber); converts it so you can print it useing a char. can you do it the other way and convert letters to numbers?

Look for strtol and strtod. Those work for converting strings into longs and doubles (respectively).

sprintf only changes char arrays, so no.
you''re looking for itoa().

int tempint;
itoa(tempint, string, base); // where base is 8, 10, or 16

Actually I think the function you are looking for is atoi, not itoa. itoa converts an int to a char, atoi converts a char to an int, which is what I believe you are looking for.
