\def\aleatorioValue{%
\ctxlua{context(math.random(1,10) < 5 and 1 or 0)}%
}
\def\aleatorioValue{%
\cldcontext{math.random(1,10) < 5 and 1 or 0}%
}
\edef\controlValue{1}
\edef\inferior{Number too small \\}
\edef\superior{Number too big \\}
\def\myfunction{\ifnum\aleatorioValue=\controlValue\relax\inferior\else\superior\fi}
