      NAME
           hypot - Euclidean distance function

      SYNTAX
           #include <math.h>

           double hypot (x, y)
           double x, y;

      DESCRIPTION
           Hypot returns

                sqrt(x * x + y * y),

           taking precautions against unwarranted overflows.

      DIAGNOSTICS
           When the correct value would overflow, hypot returns HUGE
           and sets errno to ERANGE.

           These error-handling procedures may be changed with the
           function matherr(3M).

      SEE ALSO
           matherr(3M), sqrt(3F).
