With the new web-interface default that the browser number input is used by default we see problems entering numbers with digits after the decimal point. The reason is probably that the browser with a german (or austrian) locale insists that a number must contain digits after a decimal *comma* (german and austrian locales have a decimal comma not a decimal point). Which in turn cannot be parsed by roundup's mechanisms. So we can neither enter a decimal comma (because the cgi mechanisms cannot parse this) nor a decimal point (because the browser won't let us). When, e.g., entering "3.5" the browser issues the message "Please enter a valid value. The two nearest valid values are 3 and 4."

So I guess we should make the config-setting
use_browser_number_input
defaulting to "no" not "yes" as it currently doesn't work for non-english locales

It might also be that some browsers allow only integers or that I've made an error when refactoring the html generation with the new config variable. I've not investigated further. The browser in use is probably Chrome.
