Thanks! I've been able to use this code as a basis to create a set of formats rounding evenly to different decimal places, which should save me a lot of time in the future. In answer to some of the other questions, rounding to even only applies in the case of tie breakers e.g. the third decimal place is 5 when your rounding to 2d.p. Therefore 1.615-> 1.62, 1.625->1.62. All other cases would be rounded as you would normally expect, so 1.633->1.63. From what I know, rounding to even is the statistically safer way of rounding. It is also the way R rounds by default which is why I need to achieve the same in SAS.
