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.)
–1
SIN ( S+3 S+2
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 won't be exe-
cuted.
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.
