HYPOT(S)                 XENIX System V                  HYPOT(S)



     Name
          hypot, cabs - Determines Euclidean distance.

     Syntax
          #include <math.h>

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

          double cabs (z)
          struct {double x, y;} z;

     Description
          hypot and cabs return:

               sqrt(x*x + y*y)

          Both take precautions against unwarranted overflows.

     See Also
          sqrt in exp(S), matherr(S)

     Diagnostics
          When the correct value reaches overflow, hypot returns a
          HUGE value and sets errno to ERANGE.

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

     Notes
          These routines must be linked by using the -lm linker
          option.
