Detailed Description

Function Documentation

subroutine dlabad (double precision small, double precision large)

DLABAD

Purpose:



 DLABAD is a no-op and kept for compatibility reasons. It used


 to correct the overflow/underflow behavior of machines that


 are not IEEE-754 compliant.

Parameters

SMALL 



          SMALL is DOUBLE PRECISION


          On entry, the underflow threshold as computed by DLAMCH.


          On exit, the unchanged value SMALL.

LARGE
