Approximation of Sine function in Integer Forth

[Martin Hepperle]

Thank you for your comments!

For starting, I have implemented Garth's Forth code and added the result to the deviation plot.

The overall deviation is much lower than my piecewise approximation but due to exploiting the full range for scaling, Garth's result is also much smoother.

[edit: the attachment in my initial post was updated accordingly]

[the only change I made to Garth's code was to replace -1 SHIFT by 1 RSHIFT in the word U*/_RND as my Forth only has RSHIFT and LSHIFT]
