How can I get the digits out of an interger
ex
if a = 255 then I want to, b = 2, c = 5, d = 5. In pic basic you could just do
b = a dig 0
is there a command like this in c or how would I do such a task |

If you want to do it w/o a function, i found this handy little function in the program i'm working on. For my purposes, it only works on a number 99 or smaller, but you can build on it.
| Code: |
// need a buff of size 2
// Preconditions: mybuff points to an int of less than 100.
void int_to_string_conv(unsigned int this_int, char *mybuff)
{
mybuff[0] = (this_int / 10) + 0x30;
mybuff[1] = (this_int % 10) + 0x30;
}
