I don't see the big problem, I think the spec is fine here. Yes it allows  
for putting a float there, but authors won't use it, so what's the  
problem? The spec already say you should use the number to calculate the  
correct intrinsic size, and the implementation will know what to do with a  
float number there if someone finds an actual use for it.

This isn't limiting it for the sake of making anything easier, it's not  
like "the x is an integer" is any easier than "the x is a float". And if  
you *do* somehow find a good use for it down the line (and I believe there  
might be, maybe 0.5x) it'll be there and work. No harm. :)
