Processing details
-1
• SIN (arcsine) operation is performed on the SIN value data specified with (S) to find an angle.
• The SIN value specified with (S) must be within the range -1.0 to 1.0.
• The operation result is in an angle (degree) unit.
• If (S) is an integer type, it is converted into a floating-point type before operation is performed.
Operation error
An operation error will occur if:
• (S) is outside the range -1.0 to 1.0.
• (S) is an indirectly specified device and its device number is outside the range.
