Is there a package that provides fixed point decimals? It seems that FixedPointNumbers.jl contains only binary fixed-point types and normed fixed-point types.

I have not seen that package. How many digits on either side of the decimal point are of interest to you?

I am looking to generalize Currencies.jl’s fixed-point decimal type to a dimensionless one; see https://github.com/JuliaFinance/Currencies.jl/pull/69. The goal is to support an arbitrary number of decimal points, backed by an arbitrary integer type.
