It started as a small task to save space for a calculator project with 1 function. Now, as of mid October 2026, fp64lib transformed into a full blown library with more than 100 functions! And it’s still growing, as the IEEE 754 standard contains a wealth of functions that should/could be implemented.
I hope you like it. If so, consider giving me a star on my github page or leave a comment in the discussion forum. I’m always happy to see, what you use the library for. This gives me additional energy to keep up maintaining and extending it.
