COSD(P)
7.12.4 COS operation on floating-point data (Double precision)
(COSD(P))
COSD(P)
Function
(1) The COS (cosine) value of the angle specified by is calculated and its result is stored into
the device specified by .
(2) Angles designated at are set in radian units (degrees / 180).
For conversion between degrees and radian values, see the RADD and DEGD instructions.
(3) When the operation results in -0 or an underflow, the result is processed as 0.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.
• The value of the specified device is not in the following range: (Error code: 4140)
0,2
-1022
| value of specified device | < 2
1024
• The value of the designated device is 0. (Error code: 4140)
• The result exceeds the following range (Operation results in an overflow):
2
1024
| Operation result | (Error code: 4141)
: Angle data of which the COS (cosine) value is obtained or head number of the devices where the angle data
is stored (real number)
: Head number of the devices where the operation result will be stored (real number)
