Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
Description
ASIND(854) computes the angle (in radians) for a sine value expressed as a
double-precision (64-bit) floating-point number 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.)
The source data must be between –1.0 and 1.0. If the absolute value of the
source data exceeds 1.0, an error will occur and the instruction will not be
executed.
The result is output to words D to D+3 as an angle (in radians) within the
range of –
π
/2 to
π
/2.
The following diagram shows the relationship between the input data and
result.
