NAME

       lapy2 - lapy2: robust sqrt( x^2 + y^2 )

SYNOPSIS

   Functions
       double precision function dlapy2 (x, y)
           DLAPY2 returns sqrt(x2+y2).
       real function slapy2 (x, y)
           SLAPY2 returns sqrt(x2+y2).

Detailed Description

Function Documentation

   double precision function dlapy2 (double precision x, double precision y)
       DLAPY2 returns sqrt(x2+y2).

       Purpose:

            DLAPY2 returns sqrt(x**2+y**2), taking care not to cause unnecessary
            overflow and unnecessary underflow.

       Parameters
           X

                     X is DOUBLE PRECISION

           Y

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