calculates the arc sine of the number. Stores the result in the destination floating-point
data register. This function is not defined for source operands outside of the range [ –
1... + 1]; if the source is not in the correct range, a NAN is returned as the result and
the OPERR bit is set in the floating- point status register. If the source is in the correct
range, the result is in the range of [ – /2... + /2].
NOTES:
1. If the source operand is a NAN, refer to 1.6.5 Not-A-Numbers for more information.
2. Sets the OPERR bit in the floating-point status register exception byte.
