There are no tools in arctoolbox that do that specific task.
You would need to format your output in whatever mechanism you are using to produce output.
within text files you could round, truncate and a variety other things.
a = 1.23456789 .... python's round(a, 2) 1.23 etc
So the important question is where do you want two decimals being shown... in the input? the output? and in either case what are they?
