Summary rgba() and hsla() opacity doesn't end up as-specified in DOM

When setting e.g. opacity: .42 on an element, retrieving that property in the DOM again returns 0.42 as expected. This doesn't work for rgba() and hsla() values. E.g. specifying rgba(0,0,0, .42) returns rgba(0,0,0, 0.417969) in the DOM, the same for hsla(). This is inconsistent and unexpected.

This probably happens because opacity is stored as a float and the alpha component of a color is stored as a byte.

Using STP163, I get opacity and rgba as 0.42 in computed tab of Developer Tools? Do we need anything else or we can close this?
