COS(P)
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
(For the Basic model QCPU, High Performance model QCPU, Process CPU, Redundant
CPU)
*2: There are CPU modules that will not result in an operation error if
• The result exceeds the following range (Operation results in an overflow)

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 32-bit floating decimal point type real
numbers at D0 and D1.
