/*
* Routines for computation of basic transcendental functions sin and cos.
* These routines use only integers, hence they do not require an FPU nor any
* kind of FPU emulation. Works reasonably fast even on an 8086 CPU.
*
* The results are computed using polynomial approximations. Their precision
* is not expected to be ideal, but "good enough" for common usage.
