Seems like a helper that does a number or a percentage and converts the percentage just by dividing by 100 would simplify code in a few different places.

Could have expanded the name num to number since touching this code.

> Source/WebCore/css/parser/CSSPropertyParserHelpers.cpp:780
> +            alpha = clampTo<double>(*percent / 100.0f, 0.0, 1.0);

The "f" here seems wrong. Was in the old code too, but wrong.
