### Describe the bug According to the [Binary GCD algorithm](https://en.wikipedia.org/wiki/Binary_GCD_algorithm), its result cannot be a negative number. <img width="964" alt="截屏2024-06-24 21 31 30" src="https://github.com/apache/datafusion/assets/26053282/ff33090f-8c7c-408e-9b35-e0f975c73fa9";> ### To Reproduce ```sh DataFusion CLI v39.0.0 > select gcd(-100, 0), gcd(0, -100); +---------------------------+---------------------------+ | gcd(Int64(-100),Int64(0)) | gcd(Int64(0),Int64(-100)) | +---------------------------+---------------------------+ | -100 | -100 | +---------------------------+---------------------------+ ``` ### Expected behavior In PostgreSQL ```sh postgres=# select gcd(-100, 0), gcd(0, -100); gcd | gcd -----+----- 100 | 100 (1 row) ``` ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
