Is 1.0e-03 * 0.9734 equivalent to 0.9734 * 10^-3 = 0.0009734 ? Because I am not sure

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.

ans =
    0.0009734
