C***PURPOSE  Computes the determinant of a Band matrix using
C            the factors computed by DNBCO or DNBFA.
C***DESCRIPTION
C
C     DNBDI computes the determinant of a band matrix
C     using the factors computed by DNBCO or DNBFA.
C     If the inverse is needed, use DNBSL  N  times.
C
C     On Entry
C
C        ABE     DOUBLE PRECISION(LDA, NC)
C                the output from DNBCO or DNBFA.
C                NC must be .GE. 2*ML+MU+1 .
C
C        LDA     INTEGER
C                the leading dimension of the array  ABE .
C
C        N       INTEGER
C                the order of the original matrix.
C
C        ML      INTEGER
C                number of diagonals below the main diagonal.
C
C        MU      INTEGER
C                number of diagonals above the main diagonal.
C
C        IPVT    INTEGER(N)
C                the pivot vector from DNBCO or DNBFA.
C
C     On Return
C
C        DET     DOUBLE PRECISION(2)
C                determinant of original matrix.
C                Determinant = DET(1) * 10.0**DET(2)
C                with  1.0 .LE. DABS(DET(1)) .LT. 10.0
C                or  DET(1) = 0.0 .
