R: First result word
When the execution condition OFF, ACOS(464) is not executed. When the
execution condition is ON, ACOS(464) computes the angle (in radians) for a co-
sine expressed as the 32-floating-point content of S and S+1, and places the
result in R and R+1.
–1
COS S+1
R+1
The result is output to words R+1 and R as an angle (in radians) within the range
of 0 to π.
The cosine must be floating-point data within the range of –1.0 to 1.0.
Note Refer to page 115 for general precautions on operand data areas.
