@Omega359 During the code review, I found that it is possible to implement support cast for all numeric values (Int/Float/Decimal) to string view. I thought it would be good to implement it in 1 PR instead of creating new issue for each datatype -> so I implemented it in this PR. How do you think about it? If it fine, could you please update the issue description?
