fp64lib is a library for implementing 64-bit floating point arithmetic on the AVR MegaAVR architecure microprocessors, like the popular Arduino series. Data format is fully compatible with IEEE 754 binary64 standard, providing about 15-17 digits of accuracy.
The library comes with a math.h compatible head file named “fp64-math.h”. All fp64lib routines start with “fp64_”, e.g. fp64_sin or fp64_add. Library is fully compatible to usual “math.h” routines and include functions for basic arithmetic, checking and comparing, trigonometry, conversion, logarithms and hyperbelic math. Read more…
