Well, numbers in javascript are all floating point, from the practical point 
of view. There is a relatively recently added optimization that treats most 
integer numbers as a special case, but I don't think it uses integer math 
for the calculation, so I think asking for soft-float would be an 
improvement, for platform missing floating point hardware.
