\surd and \sqrt: German version #147

Open juw opened 5 years ago

juw commented 5 years ago

Hi,

while upright versions of the integral symbols as used in German math typesetting are provided, only an American version of the radical symbol is provided. Examples for a German (and Russian) version can be seen at e.g. [1] (German left, Russian middle, American right). A real world example of its usage you can see e.g. at [2] and at [3] (and [4]/[5]) for the n-th (and cubic etc.) root. Would it be possible to add it as a variant?

Best regards.

This might be tricky. The size and position of the degree is controlled by values in the MATH table, so while we might be able to provide variants of the radical sign shape, we likely would not be able to vary the degree as shown in the Wikipedia example.
