In that case the monkey-patch suggestions made by others would do the  
trick for you. I personally wouldn't like to see anything like this in  
the Float class proper since it really isn't part of the float itself  
but rather an operation on the string representation of it.

Of the m-p suggestions made (is this question now mp-complete?), I  
like Pat Maddox's truncate() the best:
