I have data that are only significant to 3 figures, but are supplied to levels of specious precision.

the range can be from 0.001 to 999000.

I want to retain the underlying values but display the data to 3SF

I had thought that some sort of PICTURE format might do the job e.g.

Sig3Fig (Round) <1 = "9.999" 1-<10 = "9.990" 10-<100 = "99.90" 100-<1000 = "999" 1000-<10000 = "9990" etc

it doesn't quite cut it. Any suggestions?
