Function
(1) The COS (cosine) value of the angle specified by
(2) Angles designated at
S
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.
Error
code
The specified device value is not within the following range:
-102
4140
0, 2 | Specified device value | < 2
The specified device value is -0.
The operation result exceeds the following range (when an overflow
occurs):
4141
1024
2 | Operation result |
Program Example
(1) The following program performs a COS operation on the angle data designated by the 4 BCD digits from X20 to X2F, and
stores results as 64-bit floating decimal point type real numbers at D0 to D3.
