V1.1.0 Improved precision and better performance

All basic functions were restructured to allow access to full internal 56-bit precision. This was necessary to completely rewrite all trigonometric functions and to update logarithm and exponential functions. As a result, most higher math functions (like sin, cos, tan, asin, acos, atan, log and exp) have now increased precision and reduced execution time, still with small code size. As an example, execution time for fp64_sin is now between 600 and 650 micro seconds on a standard, 16 MHz Arduino MEGA 2560 – or 9500 to 10500 ticks (instructions).

V1.1.0 also includes some minor bugfixes and code improvements.

V1.0.5 available

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.
