Floating-point Math Instructions
Section 3-15
Description
ATAN(465) computes the angle (in radians) for a tangent value expressed as
a 32-bit floating-point number in S+1 and S and places the result in R+1 and
R.
(The floating point source data must be in IEEE754 format.)
The result is output to words R+1 and R 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.
Flags
Precautions
The source data in S+1 and S must be in IEEE754 floating-point data format.

Operation
Error Flag
ER
ON if the source data is not recognized as floating-point
data.
ON if the source data is not a number (NaN).
OFF in all other cases.
Equals Flag

ON if both the exponent and mantissa of the result are 0.
OFF in all other cases.
Overflow Flag

OFF
Underflow Flag
UF
OFF
Negative Flag
N
ON if the result is negative.
OFF in all other cases.
