Format Posit
Coding numbers in computers

The UNUM (Universal Numbers) format was introduced by J.L. Gustafson in 2015 with the aim of overcoming limitations of the IEEE 754 floating format. After the UNUM 1 and UNUM II types, which had a number of problems, the UNUM III type, known as the Posit format, was introduced in 2017 . As of 2022, there are no hardware implementations of this format apart from experiments on FPGAs. Several software libraries have been developed for this format, and a Posit working group has defined a standard for Posit arithmetic
