No one, but what should it do if you enter ENG 0? Give an error? Seems like a waste of ROM to arbitrarily limit folks choices. What should the minimum be? 3? 2? 4?

It was though much more simple to do something similar to SCI and FIX, while adjusting exponent and decimals, and so not mixing significant digits with ENG and decimals like FIX and SCI...
