(d)
COS (s) =
(d): Sign
(d)+1: Integral part
(d)+2: Decimal part
• For the value to be specified in (s), set a value from 0 to 360(in the DEG. unit) as a BCD value.
• For the sign of the operation result to be stored in the device specified by (d), 0 is stored when the operation result is
positive and 1 is stored when the operation result is negative.
• The operation result to be stored in the devices specified by (d)+1 and (d)+2 is a BCD value in the range from -1.000 to
1.000.
• The operation result is a value whose 5th decimal place is rounded off.
