After 2 years of development, reading several 100 pages of algorithms, after typing more than half a million lines of code, after creating, testing and verifying more that 19000 test cases, after endless hours/nights/weekends of hunting down nasty bugs, after documenting more than 60 top level functions, it’s finally good enough to be released as a V1.0.
The initial release of fp64lib for Atmel AVR 328 microprocessors is available here as a downloadable library for the Arduino IDE.
Have fun using it and I am pleased to receive any feedback via mail (at) fp64lib (dot) org.
