# Question: Why Is 256 A Special Number?

## What is an overflow in binary?

Overflow occurs when the magnitude of a number exceeds the range allowed by the size of the bit field.

The sum of two identically-signed numbers may very well exceed the range of the bit field of those two numbers, and so in this case overflow is a possibility..

## How is binary calculated?

To convert integer to binary, start with the integer in question and divide it by 2 keeping notice of the quotient and the remainder.
