Psion Revo uses binary coding for floating point arithmatics.

Programming the Revo in OPL is a little more troublesome than its larger brothers, the 3 and 5 series. The Revo does not have the OPL Editor build into its ROM. The editor can however be downloaded from Psion Support area .

For those of us who like to use RPN calculators, there is dCalc
Please see my Psion Series 5 page for full details.
