Using the distribution generators in the application, you can expect the obtained random numbers to belong to definitional domain of the corresponding distribution irrespective of its parameters. For example, random numbers
obtained as output of the relevant generator that are uniformly distributed on [
) are assumed to satisfy the following condition:
) for all indices
and for all values of
. However, because of the specificity of floating-point calculations and rounding modes, some continuous distribution generators may produce random numbers lying beyond definitional domain for some particular values of distribution parameters. This is not acceptable in applications for which accuracy of calculations is critical.
