### What are the place values in a number? (Definition)

The rank of a digit in a number (unit, ten, hundred, etc.) is the name of the position of the digit within the number, relative to its integer part (before the decimal point) or to its decimal part (after the decimal point).

Each number in a number can be associated to a a name that describes its position, its rank. The best known are the numbers of the units, tens, hundreds, thousands for integer numbers, or the numbers of the tenths, hundredths, thousandths, etc for decimal numbers. but there are others (all of them can be described). Here is a list/chart/table in English:

 1 Units (Once) Digit 1 10 Tens (Tence) Digit 2 100 Hundreds Digit 3 1000 Thousands Digit 4 10000 Tens of Thousands Digit 5 100000 Hundreds of Thousands Digit 6 1e+06 Millions Digit 7 1e+09 Billions Digit 10 0.1 Tenths 1st decimal place 0.01 Hundredths 2nd decimal place 1 Thousandths 3rd decimal place 0.0001 Ten-Thousandths 4th decimal place 1e-05 Hundred-Thousandths 5th decimal place 1e-06 Millionths 6th decimal place 1e-09 Billionth 9th decimal place

Example: 1.2 for 1 unit and 2 tenths
0.005 for 5 thousandths
700 for 7 hundreds

NB: The place value of digit is always 10 times as great as the place value of the digit to its right.
