fp64lib

Handcrafted 64-bit floating point routines for AVR/arduino microprocessors. 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. V1.1.13 added fp64_exp10, fp64_log2 and experimental long double support for gcc 10.
