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.
