It's often useful for me to round numbers to some decimal place for printing on a graph or figure. I usually do this by:
RoundedNumber = Round[NumberToRound, 0.001]
But if the resultant rounding is say
1.19, I would like to keep the trailing zero; so
1.20. The reason being is that I represent by errors in bracketed notation -- where the number in brackets represents the error in the last digit. E.g.
1.20(2) -- so as you can see it is important to keep the trailing zero as
1.2(2) has a different meaning to
Does anyone a way I can do this?
