Convert getdate() to int
This is because SQL natively keeps the number of days since 01/01/1900
The decimal after the integer value is the time.
32.5
would equal 02/01/1900 12:00 pm
If you are looking to get and work with only part of the date as an integer I would recommend using datepart
This statement would return only the month and convert that value to an integer.
select convert(int, datepart(mm,getdate())
