class std::piecewise_constant_distribution< _RealType >"A piecewise_constant_distribution random number distribution.

This distribution produces random numbers $ x, b_0 leq x < b_n $, uniformly distributed over each subinterval $ [b_i, b_{i+1}) $ according to the probability mass function  [
 p(x | b_0, ..., b_n, rho_0, ..., rho_{n-1})
   = rho_i cdot ac{b_{i+1} - x}{b_{i+1} - b_i}
     + rho_{i+1} cdot ac{ x - b_i}{b_{i+1} - b_i} ] for $ b_i leq x < b_{i+1} $.
