I'm trying to find the nth digit of an integer of an arbitrary length. I was going to convert the integer to a string and use the character at index n...

char Digit = itoa(Number).at(n);

...But then I realized the itoa function isn't standard. Is there any other way to do this?

(number/intPower(10, n))%10
