show mexp(256); % outputs e; since MF uses mexp(x) = exp(x/256)
show 3.14159; % no pi constant built in; of course we can define it
% in several ways... even computing
% C/2r (which would be funny since MF handles paths,
% and a circle is a path...)
show sqrt2; % 1.41422, or in general sqrt(a)
show mexp(256*x); % see e.
show abs(x); % returns |x| (the absolute value of the number x, or
% the length of the vector x); it is the same as
% length(x); plain Metafont in fact says:
% let abs = length;
show floor(x); % floor
show ceiling(x); % ceiling
show x**y; % ** is not a built in: it is defined in the basic macros
% set for Metafont (plain Metafont) as a primarydef
