It compiles without errors. Some conversion functions, multiply, and sine have been tested for the lfix_t type.
Original authors: Maximilian Rosenblattl and Andreas Wolf. Their work may be found here.
Their library was meant to be compiled as a static .a file. Arduino doesn't have the ability to include pre-built .a files as libraries. I am in the process of porting the code to be compatible with Arduino.
I am also fixing several bugs.
- type conversions
- multiplication
- division
- absolute value
- rounding
- countls (What is this? I don't know yet.)
- square root
- sine/cosine/tangent
- arctangent/arctangent2
- log 2/e/10
The source library is missing exponentiation. Hopefully someone can find the time to add it.
I'm not totally sure yet how everything works, but I have one example sketch.
- Verification/testing -- do the functions actually work?
- Profiling -- is this actually faster than floating point math?
- Implement exponentiation --
