COSD(852) calculates the cosine of the angle (in radians) expressed as a
double-precision (64-bit) floating-point value in words S to S+3 and places the
result in words D to D+3.
(The floating point source data must be in IEEE754 format.)
COS( S+3 S+2
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 will not 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.
