returns a sample from a Gaussian distribution

Detailed Description

template<class RNG> class QuantLib::BoxMullerGaussianRng< RNG >

Gaussian random number generator.

It uses the well-known Box-Muller transformation to return a normal distributed Gaussian deviate with average 0.0 and standard deviation of 1.0, from a uniform deviate in (0,1) supplied by RNG.

Class RNG must implement the following interface:

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