This is part 7 of the onboarding floating point series. This series is intended to be used for onboarding of programmers new to the team to review a basic understanding of fixed-point and floating-point number formats, or for programmers who would like to remove some of the mystery from formats they may use everyday.

Some floating-point formats have standard names. Unless specified otherwise, it would be expected that:

  • “float” is the IEE-754 form of s23e8

  • “double” is the IEE-754 form of s52e11.

  • “half” is the IEE-754 form of s10e5.

Next: Part 8

Two's-complement fixed-point Basic Math - Fixed-point values are fractions. Basic math with fixed-point values is basic math with fractions.
