I have a set of calculated results that I need to round to two significant figures. The rounding rules that I need to use are 5 and above rounds up and below 5 rounds down (I'm not taking into consideration whether or not the number before the 5 is odd or even). For example, I would need to round 0.04255 to 0.043 and 0.0255813953 to 0.026 etc. What is the best way to do this?
