I’m trying to add `Decimal`

support to my database package; in order to load decimals into a table, this requires having a fixed Decimal definition such as the following:

`create table test (col1 Decimal(7,4));`

Within Julia, you can have `Decimal[]`

where all of the exponents are different:

```
julia> decvec = Decimal[decimal(1.4549875498754), decimal(1.7), decimal(145498.75498754)]
3-element Array{Decimal,1}:
Decimal(0, 14549875498754, -13)
Decimal(0, 17, -1)
Decimal(0, 14549875498754, -8)
```

Is there an already implemented way of standardizing the precision and scale? If this doesn’t exist and I do this myself, do I have to worry about floating-point error? I’m generally not a `Decimal`

user, so I don’t want to make an erroneous assumption for those of you who care about exactness.
