-FUNCTION
-        <<atan>>, <<atanf>>---arc tangent
-
-INDEX
-   atan
-INDEX
-   atanf
-
-ANSI_SYNOPSIS
-        #include <math.h>
-        double atan(double <[x]>);
-        float atanf(float <[x]>);
-
-TRAD_SYNOPSIS
-        #include <math.h>
-        double atan(<[x]>);
-        double <[x]>;
-
-        float atanf(<[x]>);
-        float <[x]>;
-
-DESCRIPTION
-
-<<atan>> computes the inverse tangent (arc tangent) of the input value.
-
-<<atanf>> is identical to <<atan>>, save that it operates on <<floats>>.
-
-RETURNS
-@ifnottex
-<<atan>> returns a value in radians, in the range of -pi/2 to pi/2.
-@end ifnottex
-@tex
-<<atan>> returns a value in radians, in the range of $-\pi/2$ to $\pi/2$.
-@end tex
-
-PORTABILITY
-<<atan>> is ANSI C.  <<atanf>> is an extension.
