# IEEE754tools
|
2020-11-27 11:16:22 +01:00
|
|
|
|
|
|
|
|
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.

|
|
|
|
|
|
|
|
- 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
|
|
|
|
|
|
2021-01-29 12:31:58 +01:00
|
|
|
- investigate other speedups
|
|
|
|
|
- write more examples
|
|
|
|
|
- test on ESP32
|
|
|
|
|
- test with double
|
|
|
|
|
- binary transfer over Serial
