Approximation of Sine function in Integer Forth

[Martin Hepperle]

For my purpose, Garth's solution is very usable and "good enough" (famous last words ;-)).
It also fits nicely on a single Forth screen, has only a small memory footprint and takes about the same time as my initial, poor approximation.

I don't need "absolute" accuracy - in this case I would probably consider something like Cordic and a floating point number representation.

In the first update of my PDF document I had Garth's solution overlaid with wrong scaling on the horizontal axis, mapping 0...360 deg to my scale of 0...90 deg. I noticed my mistake and had corrected the document half an hour later, so maybe Thomas downloaded the incorrect, intermediate version?
