float atan2d ( float  y, float  x  )

inline

Compute arc tangent with 2 parameters (degrees).

Computes the principal value of the arc tangent of y/x, expressed in degrees. To compute the value, the function uses the sign of both arguments to determine the quadrant.

Parameters

y	Floating point value representing a y coordinate.
x	Floating point value representing an x coordinate.

Returns

Arc tangent of y/x, in the interval [-180,+180] degrees.

Warning

This function requires the enhanced NBC/NXC firmware.
