s (IN)
d
Processing details
■Operation processing
• These functions calculate the arc sine (SIN
(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=SIN A
• Input a REAL data type value to (s) within the following range.
ASIN: -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).
Operation error
Error code Description
3402H The data specified by (s) is -0.
3405H The value input with ASIN is other than -1.0 to 1.0.
