Float to Datetime Conversion

I need to convert values in a float data type field to that of datetime. The float data type field currently contains values such as 20060927,20060928, etc. Any suggestions?
Thanks in advance,
sajmeraconvert(datetime,cast(cast(foo as integer) as char),112)|||Thanks for the quick reply. I also tried the following and got the result.

convert(datetime,convert(varchar(20),convert(int,c onvert(float,<field name>))))

Thanks again!|||SELECT CAST(CONVERT(VARCHAR, Col1) AS DATETIME) AS NewValue
