What will be the output of below Sql-server query?

SELECT CAST(CAST(205.45 AS varbinary(20)) AS decimal(10,5));

Output will be 205.45000.

As we have cast 205.45 to decimal(10,5),means it will be be treated as 5 decimal places,so after decimal point it will be 5 decimal places,so 205.45 will be 205.45000
