FizzBuzz of first 100 numbers written using TeX macros. TeX is a very strange programming language, but hey it works...

	% Compile with pdftex, not pdflatex


	\def\modulo#1#2{(#1-(#1/#2)#2)} % a mod n = a-(a/n)n where / is integer division

	\newcount\X
	\X=1
	\loop
	\ifnum \numexpr\modulo{\X}{15} = 0
	FizzBuzz
