Float numbers

[Duncan McQueen]

Is it correct that to get a float variable, you should check to make
sure it is a float and then do a getRaw? Other methods seem to strip
the decimal point.

[Ed Finkler]

I believe so, yes, but that's really a problem -- we shouldn't be
forcing people to do getRaw in a case like that, since it should be
possible to construct a whitelist regex for it. You could use getRegex
for now to avoid doing a getRaw, but if you want to offer a patch to
add a getFloat, that would be awesome too.
