I have bee recently doing some work on calcuclated fields in lists and was getting frustrated by a lack of doco of what functions were available on the web. Well this is probably obvious to all of you but I actually found all the information I needed supplied with the Sharepoint Help feature!!!!!!!
In the Add new Column page I selected the Show more information link in the Optional settings for columns and followed the path to Calculated fields functions. Its quite good.
