SINQ/COSQ/TANQ
z TANQ
TANQ(477) calculates the tangent of the angle (in radians) expressed as a 32-bit floating-point value in
S+1 and S and places the result in R+1 and R.
(The floating point source data must be in IEEE754 format.
• Specify the desired angle (-65,535 to 65,535) in radians in S+1 and S.
For information on converting between degrees and radians, see 3-15-9 DEGREES TO RADIANS:
RAD(458) and 3-15-10 RADIANS TO DEGREES: DEG(459).
• If the angle is outside of the range -65,535 to 65,535, an unpredictable value will be output, but the
Error Flag will not be turned ON.
• If the absolute value of the result is greater than the maximum value that can be expressed as
floating-point data, the result will be output as ±∞ or 0.
The following diagram shows the relationship between the input data and result.
