This is a feature/enhancement request to the OOCalc cell formats. For the
scientific format, please add an option to cause the scientific format to favor
certain exponential terms. This is requested because most scientific work ends
up working on powers of 1000 (meters vs kilometers vs millimeters vs
micrometers) and it would be helpful to be able to get the scientific cell
format to round to the nearest thousand. I.E.:

.0123 -> 12.3 E-3
.123 -> 123.0 E-3
1.23 -> 1.23 E+0
12.3 -> 12.3 E+0
123  -> 123.0 E+0
1230 -> 1.23 E+3

And so on. This helps with data analysis since there's many fewer conversions to
do in one's head while reviewing results. My suggestion is to add a checkbox for
rounding the exponent to the nearest power of 3 or adding an additional entry
box for what it's rounding to.
