Decimal column type is rather new for clickhouse.
I've implemented it in 1.1.15, you could grab this version from nuget to test.
Column data range is limited to 10^28 - this is .NET platform limitation. If you wish you could improve my code with BigDecimal support to extend range to clickhouse's Decimal128 10^38 although yandex docs states that Decimal128 is a big performance hit. (See DecimalColumnType.Read and .ctor)
Another limitation is precision loss upon inserts, e.g. I'm inserting value 666 with precision 10 and get 668.6100869842. (See DecimalColumnType.Write)
