You can multiply and use integers but it's a bit ugly. Especially if you work across systems, you'll always need to store notations on the multiplier used. Having a decimal as a built in type with that information stored would be much easier.
But in the end I tend to use that for most numbers, especially as compression in time series also often better works on integers than floats if you have gradual changes in the numbers.
