Description
−1
SIN (the arcsine) of the value specified in S, S+1, and S+2 is calculated, and the result (an angle) is stored
in D.
−1
SIN ([S] [S+1]. [S+2]) → [D]
S: Sign
S+1: Integer value
S+2: Decimal
Set 0 for the sign in S when the data to be processed is positive, and set 1 for the sign when the data is
negative.
Set the integer and decimal parts of the data each within a range of 0 to 1.0000 in S+1 and S+2.
The result of the calculation will be stored in D as a BCD value within the range 0° to 90° or 270° to 360° (in
degrees).

Turns on and stays on when:
Turns on for an instant when:
− The area specified using the index modifier exceeds the limit.
− If data specified in S+2, S+1 and S are not BCD value.
− If data specified in S+2, S+1 and S are not within −1.0000 to 1.0000.
Turns on when result of processing is recognized as "0."
