lapy3 - lapy3: robust sqrt( x^2 + y^2 + z^2 )
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).
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 is DOUBLE PRECISION
Y
Y is DOUBLE PRECISION
Z
Z is DOUBLE PRECISION
X, Y and Z specify the values x, y and z.
