Floating-point Math Instructions Section 3-15
Description SIN(460) calculates the sine 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 error will occur and the
instruction will not be executed. For information on converting from degrees to
radians, see 3-15-22 LOGARITHM: LOG(468) DEGREES TO RADIANS:
RAD(458).
The following diagram shows the relationship between the angle and result.
