d'Hondt PR
The d'hondt algorithm is the seat allocation method used for European parliament elections in most
European countries, including the UK. This site provides calculators that, given a set of voting
figures, will derive the associated seat allocations.
Online d'Hondt calculators
Two different online d'hondt calculators are provided here:
The PHP version does calculations server-side, but it is compatible with pretty much every web browser
out there. It is also the version to use if you intend to pass around URLs for specific result sets, or
want to change which party names/colours are used.
The client-side version does calculations without server call-outs, so it is the preferred version
if you intend to experiment with different voting figures. However browsers other than recent versions of
Firefox may have problems running it, particularly the AJAX used for past election results.
Offline d'Hondt calculator
An offline Windows-based is (still) available, although it is semi-deprecated in favour of the online versions:
This offline calculator was first written for Windows95 back in 1998, and apart from a
small bugfix the code has not been updated since circa 2002. Might get round to building 64-bit
(and possibly Windows Mobile) versions at some point though..
