Just a minor update to fix segment name and an obsolete function.
I fixed a bug that caused incorrect rounding when there was a carry over across all digits, including the one before the decimal point. Check out the latest version via the Arduino library manager.
It took quite some time from the first implmentation of a 64-bit multiplication to the full blown library. I have documented some of the history of why and how fp64lib was created, including some design decisions. Find out more under Documentation / History.
I fixed some bugs, converted fp64_atof from macro to a function and included some small examples. Check out the latest version, via the Arduino library manager.
