Describe the bug

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",
]
