This is the way you can display the currency data type

temp = float((long(Rst.Fields.Item(i).Value[1])&0xFFFFFFFFL) |
(long(Rst.Fields.Item(i).Value[0])<<32)) /1e4
locale.format('%.2f',temp, 1)

Not sure if this is the best way, but it should work.

import struct

hi, lo = (4, -474836480)
value = struct.unpack('q', struct.pack('II', lo, hi))
print value

>>
21000000000
