NAME

       lapy3 - lapy3: robust sqrt( x^2 + y^2 + z^2 )

SYNOPSIS

   Functions
       double precision function dlapy3 (x, y, z)
           DLAPY3 returns sqrt(x2+y2+z2).
       real function slapy3 (x, y, z)
           SLAPY3 returns sqrt(x2+y2+z2).

Detailed Description

Function Documentation

   double precision function dlapy3 (double precision x, double precision y, double precision z)
       DLAPY3 returns sqrt(x2+y2+z2).

       Purpose:

            DLAPY3 returns sqrt(x**2+y**2+z**2), taking care not to cause
            unnecessary overflow and unnecessary underflow.

       Parameters
           X

                     X is DOUBLE PRECISION

           Y

                     Y is DOUBLE PRECISION

           Z

                     Z is DOUBLE PRECISION
                     X, Y and Z specify the values x, y and z.
