calculates both the sine and the cosine of that number. Calculates both functions
simultaneously; thus, this instruction is significantly faster than performing separate
FSIN and FCOS instructions. Loads the sine and cosine results into the destination
floating-point data register. Sets the condition code bits according to the sine result. If
FPs and FPc are specified to be the same register, the cosine result is first loaded into
the register and then is overwritten with the sine result. This function is not defined for
source operands of
If the source operand is not in the range of [ – 2 ... + 2 ], the argument is reduced to
within that range before the sine and cosine are calculated. However, large arguments
may lose accuracy during reduction, and very large arguments (greater than approxi-
