Detailed Description

The uniform distribution on the [a,b) interval.

The pseudo-random numbers are uniformly distributed on an interval from the lower bound "a" upto "b" - the interval [a,b).

\begin{eqnarray*} \mbox{PDF } u(x) &= \left\{ \begin{array}{ll} 0, & x < a \mbox{ or } x \ge b, \\ \frac{1}{b-a}, & a \le x < b , \\ \end{array} \right. \\ \mbox{CDF } U(x) &= \left\{ \begin{array}{ll} 0, & x < a , \\ \frac{x-a}{b-a}, & a \le x < b , \\ 1, & x \ge b . \end{array} \right. \end{eqnarray*}
