I think it is Scientists that use scientific notation. It makes the calculation of numbers much easier, particularly if there are several numbers.

Consider 312 x 3012 x 2043004 x 17 =? becomes [and check my math]

3.12x102 x 3.012x103 x 2.043004x106 x 1.7x101 = ?

Now multiply the small (decimal) numbers, and add the powers to get the answer.

3.12 x 3.012 x 2.043004 x 1.7 x 1012. = 3.263831x101x1012 = 3.263831x1013.

That's a lot easier than trying to manipulate all those zeroes on the page!
