I'm not sure it's that simple. In particular, the way browsers actually _store_ the alpha value is not as an infinite-precision decimal (which is what <number> is in CSS). For example, in the case of Gecko the alpha value is stored as an integer in the range [0,255]. When serializing we do a floating-point division by 255 and then try to make the result not have 6 useless significant figures (in fact I believe we always output either 2 or 3). This is quite different from other <number> uses.... -Boris
