The fundamental constants that make up the SI system are: * 9.192631770e9 * 2.99792458e8 * 6.62607015e−34 * 1.602176634e−19 * 1.380649e−23 * 6.02214076e23

The fundamental constants that make up the SI system are: * 9.192631770e9 * 2.99792458e8 * 6.62607015e−34 * 1.602176634e−19 * 1.380649e−23 * 6.02214076e23 * 6.83e2 A floating-point system is capable of representing all of these numbers with the same relative accuracy, independent of the fact that the scale is over 50 decimal (and 150 binary) digits apart from smallest to lowest. A fixed point number cannot do the same; it only works well when the numbers you are operating on are approximately all the same scale.
