A number is written in scientific notation when it is in the form
  a*10b.

It is "normalized" when |a| ≤ 1. You would probably call this "proper" scientific notation.

Examples
  100 = 1*102
  -10 = -1*101
  1 = 1
  .1 = 1*10-1
  6,543,210 = 6.54321*106

If trailing zeros are significant, they should be included in the number. Example: 6.02300*1023.

When superscripts are not available, the multiplier can be shown using the exponentiation operator (^).  Example: 6.023*1023 = 6.023*10^23.

For some computer uses, the multiplier base and exponentiation operator are represented using an "e". This is not recommended for general writing. Example: 6.023e23
