Double-precision Floating-point Instructions (CS1-H, CJ1-H, CJ1M, or CS1D Only)
Section 3-16
Description
ATAND(856) computes the angle (in radians) for a tangent value expressed as
a double-precision (64-bit) floating-point number in words S to S+3 and places
the result in D to D+3.
(The floating point source data must be in IEEE754 format.)
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.
