float atand ( float  x )

inline

Compute arc tangent (degrees).

Computes the principal value of the arc tangent of x, expressed in degrees. In trigonometrics, arc tangent is the inverse operation of tangent. Notice that because of the sign ambiguity, a function cannot determine with certainty in which quadrant the angle falls only by its tangent value. You can use atan2d if you need to determine the quadrant.

Parameters

x	Floating point value.

Returns

Arc tangent of x, in the interval [-90,+90] degrees.

Warning

This function requires the enhanced NBC/NXC firmware.
