 A \tcode{philox_engine} random number engine produces
-unsigned integer random numbers in the closed interval \crange{0}{$m$},
-where $m = 2^w - 1$ and
+unsigned integer random numbers in the interval \range{0}{$m$},
+where $m = 2^w$ and
 the template parameter $w$ defines the range of the produced numbers.
 The state of a \tcode{philox_engine} object consists of
 a sequence $X$ of $n$ unsigned integer values of width $w$,
