name nath category Package shortdesc Natural mathematics notation. longdesc Nath is a LaTeX (both 2e and 2.09) style to separate presentation longdesc and content in mathematical typography. The style delivers a longdesc particular context-dependent presentation on the basis of a rather longdesc coarse context-independent notation. Highlighted features: longdesc depending on the context, the command \frac produces either built- longdesc up or case or solidus fractions, with parentheses added whenever longdesc required for preservation of the mathematical meaning; delimiters longdesc adapt their size to the material enclosed, rendering \left and longdesc \right almost obsolete.
