Operand Specifications
Description
COSQ(476) calculates the cosine of the angle (in radians) expressed as a 32-
bit floating-point value in S+1 and S and places the result in R+1 and R.
(The floating point source data must be in IEEE754 format.)
Specify the desired angle (–65,535 to 65,535) in radians in S+1 and S. If the
angle is outside of the range –65,535 to 65,535, an unpredictable value will be
output, but the Error Flag will not be turned ON. For information on converting
between degrees and radians, see
3-15-9 DEGREES TO RADIANS:
RAD(458)
and
3-15-10 RADIANS TO DEGREES: DEG(459)
.
The following diagram shows the relationship between the angle and result.
