                      Repeating decimal

                      Reading time: 1min

                      There are two common styles for indicating a repeating decimal in a decimal expansion of fractions like ⅓. The most common style puts a line above the part that repeats and the other style puts dots on the first and last digits of the part that repeats. Both are easy to write as shown below:

                      <mstack stackalign="right"> <msline length="6"/> <mn> 0.4047619 </mn> </mstack>
                      <mstack stackalign="right"> <msrow> <mo>.</mo> <none/><none/><none/><none/> <mo>.</mo> </msrow> <mn> 0.4047619 </mn> </mstack>
