-FUNCTION
-        <<tan>>, <<tanf>>---tangent
-
-INDEX
-tan
-INDEX
-tanf
-
-ANSI_SYNOPSIS
-        #include <math.h>
-        double tan(double <[x]>);
-        float tanf(float <[x]>);
-
-TRAD_SYNOPSIS
-        #include <math.h>
-        double tan(<[x]>)
-        double <[x]>;
-
-        float tanf(<[x]>)
-        float <[x]>;
-
-
-DESCRIPTION
-<<tan>> computes the tangent of the argument <[x]>.
-Angles are specified in radians.
-
-<<tanf>> is identical, save that it takes and returns <<float>> values.
-
-RETURNS
-The tangent of <[x]> is returned.
-
-PORTABILITY
-<<tan>> is ANSI. <<tanf>> is an extension.
