CAST/CONVERT function in Access

There is no CAST/CONVERT function in Access. But you can find a few equivalents for the convertion functions.

For example:

Cint(x)–CONVERT(smallint,x)

Clng(x)–CONVERT(int,x)

 Cstr(x)–CONVERT(varchar,x)

Cdbl(x)–CONVERT(float,x)

You can find more VBA functions  from Office Help files (within Access) if you need other data type conversion.
