■Usable data
: Usable
■Description, data type of result
• SIN
-1
(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.
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.
■Program which performs the SIN
-1
(arcsine) operation of D0 and substitutes the result to #0F
