Operation processing
• These functions calculate the arc sine of the REAL type data input to (s), and output from (d).
• These functions are expressed as follows when the input value is "A" and the output operation result is "B".
• A value input to (s) is the REAL type data value and within the following range.
• A value (angle) in radians (angle
/180) is output from (d).

Operation result
1.
Function without EN/ENO
The following table lists the operation results.
2.
Function with EN/ENO
The following table lists the execution conditions and operation results.
*1
When FALSE is output from ENO, data output from (d) is undefined. In that case, modify a program so that the data output from (d) is
not used.
