Detailed Description

Random number generator.

A port of an algorithm by Johannes Baagøe baago.nosp@m.e@ba.nosp@m.agoe..nosp@m.com, 2010 and Tommy Ettinger (tommy.nosp@m..ett.nosp@m.inger.nosp@m.@gma.nosp@m.il.co.nosp@m.m)

Variable Documentation

alea

var alea

alea creates a function that is functionally equivalent to Math.random.

That is, successive calls of the returned function return Number values with positive sign, greater than or equal to 0 but less than 1, chosen pseudo-randomly with approximately uniform distribution over that range.

The internal state of random, and hence the sequence of pseudo-random numbers it returns, is determined by the arguments to alea. Two functions returned by calls to alea with the same argument values will return exactly the same sequence of pseudo-random numbers. String and Number arguments should provide repeatable output across platforms. Object arguments[3] provide repeatable output on the same platform, but not necessarily on others.

Please call alea() with at least one argument, the implementation with nno arguments described by Baagøe was not implemented here. This provides easy means to provide somewhat unpredictable numbers, like Math.random does.

Example usage: let module_prng = alea(domainHash, "MyModuleName"); module_prng();
