Nath – Nat­u­ral math­e­mat­ics no­ta­tion

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