I know this is super simple for most of you, but I'm having trouble.

My BPM tags are written in xxx.xx format, with two decimal place precision.  
However, itunes mac chokes on this (windows does not, go figure).

Anyway, since all BPM data is either: xx.xx or xxx.xx I'd like to simple remove the last three characters.

Simple, huh?

Extra points for rounding the integer part up or down.

thanks!!
