how can I set up engineering notation in numbers '09?

I am taking some electronics courses in college and need to be able to use engineering notation ie: 1E-3, 9E6, etc. How can I best set this up in Numbers '09? All of my entries are automatically being formated as scientific notation (not multiples of 3) and the only other option I can find is just standard numbers. Thank you for your assistance.

Numbers '09-OTHER, Mac OS X (10.7.3)

My solution will be like this. ( checked on Numbers 3.6.2 )


B := LOG10( ABS( A ) )

just to simplify the formula for C

C := IF( B ≥ 0, FLOOR( B , 3 ), CEILING( B, −3 ) )

with special cell format for leading 0 and plus sign

D := FIXED( A ÷ (10^C) , 2 ) & "E" & C

I also tested LibreOffice 5.1.5.2 ( latest stable ), which supports Excel like cell format option ( ##0.00E+00 ), however the format is not transferred to Numbers even if the spreadsheet is saved as Excel's.
