% RANDOM.TEX v.1 (Donald Arseneau)
% Generating "random" numbers in TeX.
%
% Random integers are generated in the range 1 to 2147483646 by the
% macro \nextrandom. The result is returned in the counter \randomi.
% Do not change \randomi except, perhaps, to initialize it at some
% random value. If you do not initialize it, it will be initialized
% using the time and date. (This is a sparse initialization, giving
% fewer than a million different starting values, but you should use
% other sources of numbers if they are available--just remember that
% most of the numbers available to TeX are not at all random.)
%
% The \nextrandom command is not very useful by itself, unless you
% have exactly 2147483646 things to choose from. Much more useful
% is the \setrannum command which sets a given counter to a random
% value within a specified range. There are three parameters:
% \setrannum {<counter>} {<minimum>} {<maximum>}. For example, to
% simulate a die-roll: \setrannum{\die}{1}{6} \ifcase\die... .
%
% If you need random numbers that are not integers, you will have to
% use dimen registers and \setrandimen. For example, to set a random
% page width: \setrandimen \hsize{3in}{6.5in}. The "\pointless" macro
% will remove the "pt" that TeX gives so you can use the dimensions
% as pure `real' numbers. In that case, specify the range in pt units.
% For example,
% \setrandimen\answer{2.71828pt}{3.14159pt}
% The answer is \pointless\answer.
%
% The random number generator is the one by Lewis, Goodman, and Miller
% (1969) and used as "ran0" in "Numerical Recipies" using Schrage's
% method for avoiding overflows. The multiplier is 16807 (7^5), the
% added constant is 0, and the modulus is 2147483647 (2^{31}-1). The
% range of integers generated is 1 - 2147483646. A smaller range would
% reduce the complexity of the macros a bit, but not much--most of the
% code deals with initialization and type-conversion. On the other hand,
% the large range may be wasted due to the sparse seed initialization.
