+// uniform integer distribution on a small range [min, max]
+
+/**
+ * The distribution function uniform_smallint models a \random_distribution.
+ * On each invocation, it returns a random integer value uniformly distributed
+ * in the set of integer numbers {min, min+1, min+2, ..., max}. It assumes
+ * that the desired range (max-min+1) is small compared to the range of the
+ * underlying source of random numbers and thus makes no attempt to limit
+ * quantization errors.
+ *
+ * Let \f$r_{\mathtt{out}} = (\mbox{max}-\mbox{min}+1)\f$ the desired range of
+ * integer numbers, and
+ * let \f$r_{\mathtt{base}}\f$ be the range of the underlying source of random
+ * numbers. Then, for the uniform distribution, the theoretical probability
+ * for any number i in the range \f$r_{\mathtt{out}}\f$ will be
+ * \f$\displaystyle p_{\mathtt{out}}(i) = \frac{1}{r_{\mathtt{out}}}\f$.
+ * Likewise, assume a uniform distribution on \f$r_{\mathtt{base}}\f$ for
+ * the underlying source of random numbers, i.e.
+ * \f$\displaystyle p_{\mathtt{base}}(i) = \frac{1}{r_{\mathtt{base}}}\f$.
+ * Let \f$p_{\mathtt{out\_s}}(i)\f$ denote the random
+ * distribution generated by @c uniform_smallint. Then the sum over all
+ * i in \f$r_{\mathtt{out}}\f$ of
+ * \f$\displaystyle
+ * \left(\frac{p_{\mathtt{out\_s}}(i)}{p_{\mathtt{out}}(i)} - 1\right)^2\f$
+ * shall not exceed
+ * \f$\displaystyle \frac{r_{\mathtt{out}}}{r_{\mathtt{base}}^2}
+ * (r_{\mathtt{base}} \mbox{ mod } r_{\mathtt{out}})
+ * (r_{\mathtt{out}} - r_{\mathtt{base}} \mbox{ mod } r_{\mathtt{out}})\f$.
+ *
+ * The template parameter IntType shall denote an integer-like value type.
+ *
+ * @xmlnote
+ * The property above is the square sum of the relative differences
+ * in probabilities between the desired uniform distribution
+ * \f$p_{\mathtt{out}}(i)\f$ and the generated distribution
+ * \f$p_{\mathtt{out\_s}}(i)\f$.
+ * The property can be fulfilled with the calculation
+ * \f$(\mbox{base\_rng} \mbox{ mod } r_{\mathtt{out}})\f$, as follows:
+ * Let \f$r = r_{\mathtt{base}} \mbox{ mod } r_{\mathtt{out}}\f$.
+ * The base distribution on \f$r_{\mathtt{base}}\f$ is folded onto the
+ * range \f$r_{\mathtt{out}}\f$. The numbers i < r have assigned
+ * \f$\displaystyle
+ * \left\lfloor\frac{r_{\mathtt{base}}}{r_{\mathtt{out}}}\right\rfloor+1\f$
+ * numbers of the base distribution, the rest has only \f$\displaystyle
+ * \left\lfloor\frac{r_{\mathtt{base}}}{r_{\mathtt{out}}}\right\rfloor\f$.
+ * Therefore,
+ * \f$\displaystyle p_{\mathtt{out\_s}}(i) =
+ * \left(\left\lfloor\frac{r_{\mathtt{base}}}
+ * {r_{\mathtt{out}}}\right\rfloor+1\right) /
+ * r_{\mathtt{base}}\f$ for i < r and \f$\displaystyle p_{\mathtt{out\_s}}(i) =
+ * \left\lfloor\frac{r_{\mathtt{base}}}
+ * {r_{\mathtt{out}}}\right\rfloor/r_{\mathtt{base}}\f$ otherwise.
+ * Substituting this in the
+ * above sum formula leads to the desired result.
+ * @endxmlnote
+ *
+ * Note: The upper bound for
+ * \f$(r_{\mathtt{base}} \mbox{ mod } r_{\mathtt{out}})
+ * (r_{\mathtt{out}} - r_{\mathtt{base}} \mbox{ mod } r_{\mathtt{out}})\f$ is
+ * \f$\displaystyle \frac{r_{\mathtt{out}}^2}{4}\f$.  Regarding the upper bound
+ * for the square sum of the relative quantization error of
+ * \f$\displaystyle \frac{r_\mathtt{out}^3}{4r_{\mathtt{base}}^2}\f$, it
+ * seems wise to either choose \f$r_{\mathtt{base}}\f$ so that
+ * \f$r_{\mathtt{base}} > 10r_{\mathtt{out}}^2\f$ or ensure that
+ * \f$r_{\mathtt{base}}\f$ is
+ * divisible by \f$r_{\mathtt{out}}\f$.
