std::exponential_distribution

Defined in header <random>
template< class RealType = double > class exponential_distribution;		(since C++11)

Produces random non-negative floating-point values x, distributed according to probability density function:

P(x|λ) = λe-λx

The value obtained is the time/distance until the next random event if random events occur at constant rate λ per unit of time/distance. For example, this distribution describes the time between the clicks of a Geiger counter or the distance between point mutations in a DNA strand.

This is the continuous counterpart of Template:cpp
