Thanks for pointing that out.

Though I'm yet to understand what you mean by overflow.

HiOsinachi Chukwujama

I mean integer overflow:

In computer programming, an integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower than the minimum representable value.

From en.wikipedia.org/wiki/Integer_overflow
