It looks something like this : 1.07 1.11 1.27 1.59 0.97 0.76 2.23 0.98 0.71 0.88 1.19 1.02 What I'm looking for is a way to round these numbers to the nearest 0.25, i.e. the above matrix would be transformed to : 1.00 1.00 1.25 1.50 1.00 0.75 2.25 1.00 0.75 1.00 1.25 1.00 Anyone have a clever way to do this??
