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

          LARGE is DOUBLE PRECISION
          On entry, the overflow threshold as computed by DLAMCH.
