Scientific Notation
If the number is 10 or greater, the decimal point has to move to the left, and the power of 10 will be positive. | |
If the number is smaller than 1, the decimal point has to move to the right, so the power of 10 will be negative.
Here are some examples:
10000 = 1 x 10424327 = 2.4327 x 1041000 = 1 x 1037354 = 7.354 x 103100 = 1 x 102482 = 4.82 x 10210 = 1 x 101 1 = 1001/10 = 0.1 = 1 x 10-10.32 = 3.2 x 10-1 (not usually done)1/100 = 0.01 = 1 x 10-20.053 = 5.3 x 10-21/1000 = 0.001 = 1 x 10-30.0078 = 7.8 x 10-31/10000 = 0.0001 = 1 x 10-40.00044 = 4.4 x 10-4
