Detailed Description

template<class RNG> class QuantLib::CLGaussianRng< RNG >

Gaussian random number generator.

It uses the well-known fact that the sum of 12 uniform deviate in (-.5,.5) is approximately a Gaussian deviate with average 0 and standard deviation 1. The uniform deviate is supplied by RNG.

Class RNG must implement the following interface:

             RNG::sample_type RNG::next() const;
