Ensure returned numbers are of type number

Thanks to Felix for bringing this to my attention. Obviously there was
already a safety net for feeding progressbars and graphs... and while
this makes for a good coding practice it's not a big deal. We have
widgets of type textbox for one, and a lot of string concatenation
happens. Strings are formatted, markup is applied...
