The <code>non-decimal?</code> word is a translation of C++'s <code>nondecimal</code> function. Having multiple exit points in a word is not very efficient (yet?) in Factor, so I've tweaked it to have one exit point at the end.

=={{header|Raku}}==
Yet another poorly specced, poorly named, trivial task.

How many integers in base 16 cannot be written without using a hexadecimal digit? All of them. Or none of them.

Base 16 is not hexadecimal. Hexadecimal is ''an implementation'' of base 16.

<lang perl6>use Base::Any;
set-digits <⑩ ⑪ ⑫ ⑬ ⑭ ⑮ ⑯ ⑰ ⑱ ⑲ ⑳ ㉑ ㉒ ㉓ ㉔ ㉕>;
say (7**35).&to-base(16);

# ⑭㉒⑱⑩⑰⑰⑳⑮⑱⑳⑩⑳⑱㉒㉑⑰㉒⑫⑭⑲⑯⑩㉔⑮⑰</lang>

How many of those glyphs are decimal digits? And yet it '''is''' in base 16, albeit with non-standard digit glyphs. So they '''all''' can be written without using a hexadecimal digit.

But wait a minute; is 2 a hexadecimal digit? Why yes, yes it is. So ''none'' of them can be written in hexadecimal without using a hexadecimal digit.


Bah. Show which when written in base 16, contain a digit glyph with a value greater than 9:

<lang perl6>put "{+$_} such numbers:\n", .batch(20)».fmt('%3d').join("\n")
given (^501).grep( { so any |.map: { .polymod(16 xx *) »>» 9 } } );</lang>
{{out}}
<pre>301 such numbers:

But wait a minute. Let's take another look at the the task title. '''Base-16 representation'''. It isn't talking about Base 16 at all. It's talking about Base'''-16'''... so let's do it in base -16.

<lang perl6>use Base::Any;
put "Integers from 0 to 500 that when expressed in Base -16 in standard notation, contain an alphabetic: {+$_}\n",
.batch(20)».fmt('%3d').join("\n")

Borrowed masking concept from C++, which was much more elegant than my first solution.
<lang XPL0>func HasHex(N);
int N;
[while N do
[if (N&$F) > 9 then return true; N:= N>>4];
return false;
];

int N, Cnt;
[Cnt:= 0;
for N:= 1 to 500 do
[if HasHex(N) then
[if N<100 then ChOut(0, ^ );
IntOut(0, N);
Cnt:= Cnt+1;
if rem(Cnt/20) = 0 then CrLf(0) else ChOut(0, ^ );
];
];
CrLf(0);
IntOut(0, Cnt); Text(0, " such numbers found."); CrLf(0);
