IBM hexadecimal floating-point

IBM Hexadecimal Floating-Point is a way to store numbers on a computer. It does this by breaking the number down into smaller pieces called hexadecimal digits. Each hexadecimal digit can represent 16 different numbers, from 0 to 15. To store a bigger number on the computer we combine these hexadecimal digits together to represent the full number. IBM Hexadecimal Floating-Point is especially useful because it makes it easier for computers to store and process large numbers quickly and accurately.
