Description
The data in degrees of an angle specified in S+1 and S is converted to radians (real number data) and the
result is stored in D+1 and D.

Specifying the integer device with [S], the integer data is internally converted to real numbers before
operations continue.
When the constant K is specified in S, the operations are the same as when a integer device is specified.
