7.12 Special Function Instructions
COS operation on floating-point data (single precision)
COS(P)
*1 Applicable for the Universal model QCPU, LCPU.
Processing details
• Returns the COS (cosine) value of the angle designated by (S) and stores operation result at device number designated by
(D).
• Angles designated at (S) are set in radian units (degrees    180). For conversion between degrees and radian values,
see the RAD and DEG instructions.
• When an input value is set using a programming tool, a rounding error may occur. For precautions, refer to Page 89
Precautions.
Operation error
• In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and an error code is stored into SD0.
*2 There are CPU modules that will not result in an operation error if -0 is specified. For details, refer to Page 87 Using single/double-
precision real number data.
• Basic model QCPU: The serial number (first five digits) is "04122" or later.
(S): Angle data of which the COS (cosine) value is obtained or head number of the devices where the angle data is stored (real number)
(D): Head number of the devices where the operation result will be stored (real number)
