Skabelon:Rndfrac
This template rounds to a fraction. It takes two parameters.
- the number to be rounded (any real number)
- the denominator to be rounded to (positive integer)
Fractions are expressed in the simplest terms.
The template calls {{gcd}} and {{rndfrac/out}}.
{{rndfrac|0.1234|8}}→ 1⁄8{{rndfrac|12.65|6}}→ 12 2⁄3{{rndfrac|-9.123|20}}→ −9 1⁄10
