**Describe the bug**
It's not possible to compare Decimal and Float values. But actually both of them point to some specific value on real number line, so we can compare and that wouldn't produce any precision loss.

**How to reproduce**
Clickhouse 21.5
```
SELECT toDecimal32('11.00', 2) > 1.

Query id: f2c1cba1-748e-42ea-83ac-e117b542d576


0 rows in set. Elapsed: 0.002 sec.

Received exception from server (version 21.5.1):
Code: 43. DB::Exception: Received from localhost:9000. DB::Exception: No operation greater between Decimal(9, 2) and Float64: While processing toDecimal32('11.00', 2) > 1..
