See the section on "E-notation": https://en.wikipedia.org/wiki/Scientific_notation#

It is scientific notation, where e is shorthand for *10^.

Answer 2

[nyanphyo aung]

When you have y = Xe-3 that's a shorter way of saying y = X * 10^-3. Since multiplication distributes and the e operator only looks for the next number by default, yes, 1e-3 * X = X * 1e-3 = X * 10^-3. Likewise for addition.

1.0e+003 = 1000

Try in command window.. And no need to worry about this result..

It actually means 1.0 x 10 ^(+0.003).
