Every decimal representation of a rational number can be converted to a fraction by converting it into a sum of the integer, non-repeating, and repeating parts and then converting that sum to a single fraction with a common denominator.
|N (where N is a number) displays N digits after the decimal mark (round output to N decimal places). |-N (where -N is a negative number) replaces N digits before the decimal mark with zero (round output to nearest 10 N). |sigfig=N (where N is a positive number) to specify the number of significant digits (round output to N significant figures).
A fraction denominator can be specified to display results with a fraction where appropriate. For example, |frac=8 specifies that the value should be rounded to the nearest eighth, and that a fraction should be included if necessary. A fraction denominator must be a whole number with value 2 or more.
Compound fractions, complex fractions, mixed numerals, and decimals (see below) are not common fractions; though, unless irrational, they can be evaluated to a common fraction. A unit fraction is a common fraction with a numerator of 1 (e.g., 1 / 7 ).
Any such symbol can be called a decimal mark, decimal marker, or decimal sign. Symbol-specific names are also used; decimal point and decimal comma refer to a dot (either baseline or middle ) and comma respectively, when it is used as a decimal separator; these are the usual terms used in English, [ 1 ] [ 2 ] [ 3 ] with the aforementioned ...
In summary, every real number that is not a decimal fraction has a unique infinite decimal expansion. Each decimal fraction has exactly two infinite decimal expansions, one containing only 0s after some place, which is obtained by the above definition of [x] n, and the other containing only 9s after some place, which is obtained by defining [x ...
