20 = 20.0
Move the decimal so that only one non-zero digit is to its left.
Thus, we have
2.0 Then, multiply this times 10 raised to a positive exponent indicating the number of places the decimal was moved. So we have
2.0 x 10 1
Moving the decimal to the left is indicated by a positive exponent. Moving it to the right results in a negative exponent.
