c:\fortran> type d1mach.f90
function d1mach(i)
implicit none
double precision d1mach,dmach(5)
integer i,large(4),small(4)
equivalence ( dmach(1), small(1) )
equivalence ( dmach(2), large(1) )
data small(1),small(2) / 0,   1048576/
data large(1),large(2) /-1,2146435071/
d1mach = 0.0d0
end function d1mach
