The calculatorsThree flavours of calculators are provided:
- CGI (server-side PHP)
- Traditional server-side based calculator. Each recalculation will involve a round-trip to the webserver, which may be very slow dependent on your location and internet connection speed, but this calculator is the most compatible. It does not use any client-side scripting, and has been tested with Links.
- A downloadable Windows-based calculator intended for off-line use.
