NAME
       dlabad.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dlabad (SMALL, LARGE)
	   DLABAD

Function/Subroutine Documentation
   subroutine dlabad (double precisionSMALL, double precisionLARGE)
       DLABAD

       Purpose:

	    DLABAD takes as input the values computed by DLAMCH for underflow and
	    overflow, and returns the square root of each of these values if the
	    log of LARGE is sufficiently large.  This subroutine is intended to
	    identify machines with a large exponent range, such as the Crays, and
	    redefine the underflow and overflow limits to be the square roots of
	    the values computed by DLAMCH.  This subroutine is needed because
	    DLAMCH does not compensate for poor arithmetic in the upper half of
	    the exponent range, as is found on a Cray.

       Parameters:
	   SMALL

		     SMALL is DOUBLE PRECISION
		     On entry, the underflow threshold as computed by DLAMCH.
		     On exit, if LOG10(LARGE) is sufficiently large, the square
		     root of SMALL, otherwise unchanged.

	   LARGE

		     LARGE is DOUBLE PRECISION
		     On entry, the overflow threshold as computed by DLAMCH.
		     On exit, if LOG10(LARGE) is sufficiently large, the square
		     root of LARGE, otherwise unchanged.
