NarekDW opened a new pull request, #40040:
URL: https://github.com/apache/spark/pull/40040
### What changes were proposed in this pull request?
This PR proposes to use `BigInt` instead of `Long` datatype for conversion
of numbers between different radixes, because of this we will get rid of
overflows.
This change allows to convert big numbers, like:
```
spark-sql> SELECT
CONV(SUBSTRING('0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff',
3), 16, 10);
```
will give correct result:
`115792089237316195423570985008687907853269984665640564039457584007913129639935`
### Why are the changes needed?
Changes allow to convert big numbers among different radixes.
### Does this PR introduce _any_ user-facing change?
1. Users could convert big values by using `conv` function, without an
overflow.
2. Invalid number formats are not supported in `conv` function already.
### How was this patch tested?
By existing tests + an additional test cases were added to:
`sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/expressions/MathExpressionsSuite.scala`
`sql/catalyst/src/test/scala/org/apache/spark/sql/catalyst/util/NumberConverterSuite.scala`
