DATEADD function Issue when 2nd argument exceeds int limit

 SELECT DATEADD(year,2147483648, '2014-07-31')
	,DATEADD(year,-2147483649, '2014-07-31')

the above statement will throw the error
/*
Msg 8115, Level 16, State 2, Line 1
Arithmetic overflow error converting expression to data type int.
*/

this is due to the second argument of DATEADD fucntion i sint. So it should not exceed int max/min range value
