21deb57a4d [fix](Nereids) remove double sigature of ceil, floor and round (#22134)
we convert input parameters to double for function ceil, floor and round,
because DecimalV2 could not do these operation. Since we intro DecimalV3,
we should convert all parameters to DecimalV3 to get correct result.
For example, when we use double as parameters, we get wrong result:
```sql
select round(341/20000,4),341/20000,round(0.01705,4);
+-------------------------+---------------+-------------------+
| round((341 / 20000), 4) | (341 / 20000) | round(0.01705, 4) |
+-------------------------+---------------+-------------------+
| 0.017                   | 0.01705       | 0.0171            |
+-------------------------+---------------+-------------------+
```
DecimalV3 could get correct result
```sql
select round(341/20000,4),341/20000,round(0.01705,4);
+-------------------------+---------------+-------------------+
| round((341 / 20000), 4) | (341 / 20000) | round(0.01705, 4) |
+-------------------------+---------------+-------------------+
| 0.0171                  | 0.01705       | 0.0171            |
+-------------------------+---------------+-------------------+
```
