Detailed Description
These classes define objects which provide random or pseudorandom numbers, either from a discrete or a continuous interval. The random number generator supplied as a part of this library are all uniform random number generators which provide a sequence of random number uniformly distributed over their range.
A number generator is a function object with an operator() that takes zero arguments and returns a number.
A compliant random number generator must satisfy the following requirements.
