The value of the national debt is approximate due to exchange rates movements, interest charges, timing of payments and so on. So presenting it as an amount accurate to the nearest unit is misleading, if not dishonest. It is far more sensibly to express it in scientific notation. Unfortunately, there are many people who cannot figure out scientific notation although if they cannot do that does it matter that they don't know the national debt?
3 x 10^-24

Scientific Notation is expressed by using a number, using an exponent as a number (usually a decimal) multiplied by a 10, and an exponent (the number on the exponent is the number of zeros the number has).Example: 120,000,000 in scientific notation is 1.2 X 107
299,792,458 ms in Scientific Notation = 2.99792458 x 108 ms
0.000 000 050 in scientific notation or standard form is: 5.0 x 10-8

Scientific notation lets us express a large or a small number without having to write a lot of zeros before or after it. Try writing out 3 x 10^9000 without scientific notation.
It is: 5.0*10-8
3582 * 109 = 3.582 X 1012 ===========
Assuming you're using continental notation: 2.750.389 = 2,750389 x 106
