--

You first decide on the number of significant digits. In other words, if you need to round it.

Then you write one digit before the decimal point (if you have more than 1 significant digit) and follow with the power of 10 to make up for the scale:

With 4 significant digits, it would be 9.357 * 10^2.

Sometimes, this is written as 9.357E2.

With 3 significant digits, it would be 9.36 * 10^2.

With 2 significant digits, it would be 9.4 * 10^2.

With 1 significant digit, it would be 9 * 10^2.
