After I've made several calculators for numeral systems conversion (from the simplest one to more advanced: Conversion of decimal number to other notations, Conversion from decimal numeral system, Conversion between any bases - users often asked me, what should we do about fractional numbers, how to convert them? So, I decided to make another calculator, converting fractional numbers between different numeral systems.

This page is about converting a fraction (i.e. a ratio of two numbers, also called a rational number) into a decimal fraction and the patterns that occur in such a decimal fraction. It is interactive and you can use the calculators on this page to investigate fractions for yourself to many decimal places. No special knowledge beyond decimals and division is required.

Number

You may enter simple rational numbers with the whole portion separated from the decimal portion by a decimal point (ex. 12.25). You may also convert to fractions numbers with infinitely repeating digits by enclosing the repeating digits in parenthesis or by adding '...' at the end of the number. See the following table for examples:

 

 

 

 

, then the fraction is obtained by breaking the number into a sum of the non-repeating portion and the repeating portion. Each element is converted separately, the non repeating portion is converted as explained above, while the fraction for the repeating portion is obtained by dividing the repeating figures by a number of 9's equal to the length of the sequence, followed by a number of '0's equal to the the number of 0's between the dot and the repeating digits.
