Specify the desired angle (–65,535 to 65,535) in radians in words S to S+3. If
the angle is outside of the range –65,535 to 65,535, an error will occur and the
instruction won't be executed. For information on converting between degrees
and radians, see 3-16-9 DOUBLE DEGREES TO RADIANS: RADD(849) or
3-16-10 DOUBLE RADIANS TO DEGREES: DEGD(850) .
The following diagram shows the relationship between the angle and result.

The source data in words S to S+3 must be in IEEE754 floating-point data for-
mat.
Calculates the cosine of a double-precision (64-bit) floating-point number (in
radians) and places the result in the specified destination words.
This instruction is supported by the CS1-H, CJ1-H, CJ1M, and CS1D CPU
Units only.
