 		 #118395 - Fixed-point math
Responding to: ???'s previous message
Code the calculation with fixed-point math.

As for triangle functions, see this reference.
"A Guide to Approximations" by Jack G. Ganssle
http://www.ganssle.com/approx/approx.pdf

This reference considers the approximation with polynomial. (familiar Taylor expansion). It is done in 'double', but the algorithm is applied to fixed-point math.
