### Public Member Functions

CLGaussianRng(const RNG &uniformGenerator)sample_type next() const

returns a sample from a Gaussian distribution

## 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;`
