AVG to return floating value

My have interger type field in my table and would like to calcuate the Average resut.
I use following code.
SELECT AVG(MyIntegerField) from MyTable
The result always integer. The average result could be float, since it use sum of value divide by the number of items.
I would like to know is it possible to have ACG(IntegerField) to get float result or I need specific to ask SQL return float result.
If yes, can you please advise the sample code to do this?
Your help and information is great appreciated,
Regards,
Sourises,
