Kayvan-Zahiri opened a new issue, #14213:
URL: https://github.com/apache/gravitino/issues/14213
### Version
main branch, Python 3.12
### Describe what's wrong
The Python client rejects finite `Decimal` values with positive exponents
even when the expanded value fits Gravitino's decimal precision.
`Literals.decimal_literal(Decimal("1E+3"))` should represent 1000 as
decimal(4,0), but calculates scale -3 and fails validation.
### Error message and/or stacktrace
`ValueError: Decimal scale must be in range [0, precision (1)]: -3`
### How to reproduce
```python
from decimal import Decimal
from gravitino.api.rel.expressions.literals.literals import Literals
Literals.decimal_literal(Decimal("1E+3"))
```
### Additional context
`Decimal("-1.23E+4")` fails similarly. A locally tested fix counts
positive-exponent zeroes in precision, clamps scale to zero, and preserves the
original Decimal value. Fractional scale remains unchanged and expanded values
above 38 digits remain rejected. Reproduced with Codex assistance; no server or
credentials involved.
