You may enter numbers in scientific notation, often called exponential notation, using the "e" format common to computer programs.
1.0 x 10-6
1.234 x 1015
9.518 x 10+23
Currently, the conversions do not output the result in scientific notation. In the future, you will be able to choose how you would like the result dipsplayed, but I do not know when that project will be finished.
