\constfunc{bool}{ToDouble}{\param{double}{ *val}}
Attempts to convert the string to a floating point number. Returns \true on
-success (the number is stored in the location pointed to by {\it val}) or \false
-if the string does not represent such number.
+success (the number is stored in the location pointed to by \arg{val}) or \false
+if the string does not represent such number (the value of \arg{val} is not
+modified in this case).

Attempts to convert the string to a signed integer in base {\it base}. Returns
\true on success in which case the number is stored in the location
-pointed to by {\it val} or \false if the string does not represent a
-valid number in the given base.
+pointed to by \arg{val} or \false if the string does not represent a

The value of {\it base} must be comprised between $2$ and $36$, inclusive, or
be a special value $0$ which means that the usual rules of {\tt C} numbers are
Attempts to convert the string to an unsigned integer in base {\it base}.
Returns \true on success in which case the number is stored in the
-location pointed to by {\it val} or \false if the string does not

+location pointed to by \arg{val} or \false if the string does not
+represent a valid number in the given base (the value of \arg{val} is not
+modified in this case). Please notice that this function
behaves in the same way as the standard \texttt{strtoul()} and so it simply
converts negative numbers to unsigned representation instead of rejecting them
(e.g. $-1$ is returned as \texttt{ULONG\_MAX}).
