Don't forget the "missings"; an important consideration to practicing
statisticians!

You should supply specific examples of where you think that is not happening. Please use the %21x format to make clear what is happening at machine level.

Unless someone changed the command, my version of Stata 11 does not compress double to float when it can do so. This is also indicated in the documentation. However, I can recast a variable to float if there is no loss of precision, otherwise I have to put in the /force option to force convert with loss of precision.
