subroutine dlamc4 ( integer  EMIN,
double precision  START,
integer  BASE 
)

DLAMC4

Purpose:

 DLAMC4 is a service routine for DLAMC2.
Parameters
[out]EMIN
          The minimum exponent before (gradual) underflow, computed by
          setting A = START and dividing by BASE until the previous A
          can not be recovered.
[in]START
          The starting point for determining EMIN.
[in]BASE
          The base of the machine.
