[Solved] Recurring decimals in Math editor

[rsmooo]

I want to write 1/3 in decimal form: 0.3 with a dot above the 3

I have tried
0. dot 3
but that leaves a space between the decimal point and the 3

0.dot 3
doesn't work either

Is there a solution?

Same problem using
0. oveline 3

Try

Code: Select all   Expand viewCollapse view

dot { 0.3~  }

You can use the "nospace" modifier on a grouped object (use braces - {} - to delimit group) to avoid spacing between sub-elements:
Single digit with dot

Code: Select all   Expand viewCollapse view

nospace {0. dot 3}
nospace {0.3 dot 3}
nospace {0.3 {3 csup .}}

...and also with overline...

Code: Select all   Expand viewCollapse view

1 over 7 = nospace {0. overline {142857} }
