Processing details
■Operation processing
• These functions calculate the arc cosine (COS
from (d).
• When the input value is defined as A and the output value is defined as B, the relationship of A and B will be as follows:
-1
B=COS A
• Input a REAL data type value to (s) within the following range.
ACOS: -1.0 to 1.0
• The value (angle) is output from (d) in radians (angle×π/180).
■Operation result
The operation processing is performed. The operation result is output from (d).
