Numeric is functionally equivalent to decimal.
They have fixed precision and scale.
precision: maximum total number of decimal digits (for both left and right)
scale: number of decimal digits that will be stored to the right of the decimal point.
Example:
declare @num numeric(20,5)
set @num = 1333.2
print @num
declare @num1 numeric(20,0)
set @num1 = 1333.2
print @num1
Result:
1333.20000
1333
