IEEE754tools

Arduino library to manipulate IEEE754 float numbers fast.

Description

IEEE754tools.h contains a collection of bit-hacks to speed up a number of operations on floating point numbers on the Arduino. These bit-hacks started in 2010 (oldest code found) or maybe even earlier.

WARNING

  • If you don't need micro-second speedups do not use these code snippets.
  • code is experimental, so use with care.
  • only tested on UNO

Future

  • investigate other speedups
  • write more examples
  • test on ESP32
  • test with double
  • binary transfer over Serial

Operations
