Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
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.
Flags
Precautions
The source data in words S to S+3 must be in IEEE754 floating-point data for-
mat.
3-16-12 DOUBLE COSINE: COSD(852)
Purpose
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 CS1-H, CJ1-H, CJ1M, and CS1D CPU Units
only.
