Hey guys, 

I have code littered with round() or trunc() as follows:
println("β1: ", trunc(exp(results.minimum[2]), 3))

Is there a way to either set println() defaults or run it through a 
decorator to limit the number of decimals it dumps on screen such that i 
end up with code like the following but same results as above?
println("β1: ", exp(results.minimum[2]))

Thanks.
