**Describe the bug**
<!--
A clear and concise description of what the bug is.
-->
If I try and cast floating-point value `12345.67` to `decimal(6,2)` then I
get an error, as expected:
```
"1234567 is too large to store in a Decimal128 of precision 6. Max is 999999"
```
However, if I try and cast a `decimal(24,2)` value of `12345.67` to
`decimal(6,2)` then I do not get an error but instead have an invalid decimal
value.
``
PrimitiveArray<Decimal128(6, 2)>
[
1234567,
]
```
If I then convert this decimal to a string, it produces `1234.56` instead of
`12345.67`
```
StringArray
[
"1234.56",
]
```
