Function
ASIND
ASIND(854) computes the angle (in radians) for a sine value expressed as a double-precision (64-bit)
floating-point number in words S to S+3 and places the result in words D to D+3.
(The floating point source data must be in IEEE754 format.)
The result is output to words D to D+3 as an angle (in radians) within the range of -π/2 to π/2.
z The following diagram shows the relationship between the input data and
result.
