Decimal.normalize w/o getting into "scientific" notation?

When “normalising” Decimal numbers it’s easy fall into something like this:

Decimal.normalize(Decimal.new("10.00"))
Decimal.new("1E+1")

which is technically correct but rather unusable when all I want from this “normalisation” is getting rid of unneeded trailing zeroes (in this case the insignificant decimal part) while keeping the numbers “human readable”. Decimal.round() is not an option because sometimes the decimal part can be significant. I can imagine of course some ways of doing this “manually” but since I guess I am not the first one to have such not-so-exotic need, maybe there’s a ready solution out there?

You can do Decimal.to_string(decimal, :normal) to not get scientific formatting.
