The source data in S+1 and S must be in IEEE754 floating-point data format.
Calculates the arc cosine of a 32-bit floating-point number and places the
result in the specified result words. (The arc cosine function is the inverse of
the cosine function; it returns the angle that produces a given cosine value
between –1 and 1.)
