WebClearly, whoever designed the 24-bit floating-point format you are referring to did not choose to use the same bias system as is used in IEEE 754 binary32, since the values of the exponent bits of the two representations above do not match despite the exponents of both being represented with 8 bits (according to you). WebJul 22, 2024 · The 754 specification is a very widely adopted specification that describes how floating-point numbers should be stored in a binary computer. It is popular because it allows floating-point numbers to be stored in a reasonable amount of space and calculations to occur relatively quickly.
