-FUNCTION
- <<atan2>>, <<atan2f>>---arc tangent of y/x
-
-INDEX
- atan2
-INDEX
- atan2f
-
-ANSI_SYNOPSIS
- #include <math.h>
- double atan2(double <[y]>,double <[x]>);
- float atan2f(float <[y]>,float <[x]>);
-
-TRAD_SYNOPSIS
- #include <math.h>
- double atan2(<[y]>,<[x]>);
- double <[y]>;
- double <[x]>;
-
- float atan2f(<[y]>,<[x]>);
- float <[y]>;
- float <[x]>;
-
-DESCRIPTION
-
-<<atan2>> computes the inverse tangent (arc tangent) of <[y]>/<[x]>.
-<<atan2>> produces the correct result even for angles near
-@ifinfo
-pi/2 or -pi/2
-@end ifinfo
-@tex
-$\pi/2$ or $-\pi/2$
-@end tex
-(that is, when <[x]> is near 0).
-
-<<atan2f>> is identical to <<atan2>>, save that it takes and returns
-<<float>>.
-
-RETURNS
-<<atan2>> and <<atan2f>> return a value in radians, in the range of
-@ifinfo
--pi to pi.
-@end ifinfo
-@tex
-$-\pi$ to $\pi$.
-@end tex
-
-If both <[x]> and <[y]> are 0.0, <<atan2>> causes a <<DOMAIN>> error.
-
-You can modify error handling for these functions using <<matherr>>.
-
-PORTABILITY
-<<atan2>> is ANSI C. <<atan2f>> is an extension.
