Handy, but if you need the exact representation, my preference is float.hex, which seems to be the same as C99's %a format. >>> math.pi.hex() '0x1.921fb54442d18p+1' >>> float.fromhex(math.pi.hex()) == math.pi True Granted, it's not as easy for humans to interpret, but it's useful for certain things. -- http://mail.python.org/mailman/listinfo/python-list
