20. How are commas, periods, and spaces used to make long numbers easier to read?
ANSWER: In the United States, it is the practice to use a period as the decimal marker
and a comma to separate a string of numbers into groups of three for easier
reading. In many countries, the comma has been used in lieu of the
decimal marker, and spaces are left to separate a string of numbers into
groups of three. The SI system, taking something from both, uses the
period as the decimal marker and the space to separate a string of numbers
into groups of three, starting from the decimal point and counting in either
direction. An example is 12 345.789 99. An exception to this is when there
are four numbers on either side of the decimal point. In this case, the third
and fourth numbers from the decimal point are not separated, e.g.,
2015.1415.
