You can always multiply by a hundred, round(), and then divide by a hundred.

I know it's tedious but there was a lot of feeling in the WG that we should
have a library of a hundred functions rather than a thousand, if we were to
have a reasonable prospect of making the spec implementable (not to mention
the task of actually writing it and publishing it).
