commit 80c8e7de5698a467e6701673c3dc8c7d56cc6841
Author: Joseph Wright <joseph.wright at morningstar2.co.uk>
Date:   Wed Jul 5 16:21:42 2023 +0100

    Move part of l3fp-types to kernel
    
    This holds the parts that will be needed for
    variable and fn support, but not the rest.

+% \subsection{Support for types}
+%
+% Despite lack of documentation, the \pkg{l3fp} internals support types.
+% Each additional type must define
+% \begin{itemize}
+%   \item |\s__fp_|\meta{type} and |\__fp_|\meta{type}|_chk:w|;
+%   \item |\__fp_exp_after_|\meta{type}|_f:nw|;
+%   \item |\__fp_|\meta{type}|_to_|\meta{out}|:w| for \meta{out} among
+%     |decimal|, |scientific|, |tl|;
+% \end{itemize}
+% and may define
+% \begin{itemize}
+%   \item |\__fp_|\meta{type}|_to_int:w| and |\__fp_|\meta{type}|_to_dim:w|;
+%   \item |\__fp_|\meta{op}|_|\meta{type}|_o:w| for any of the \meta{op}
+%     that the type implements, among |acos|, |acsc|, |asec|, |asin|,
+%     |cos|, |cot|, |csc|, |exp|, |ln|, |not|, |sec|, |set_sign|, |sin|,
+%     |tan|;
+%   \item |\__fp_|\meta{type_1}|_|\meta{op}|_|\meta{type_2}|_o:ww| for
+%     \meta{op} among |^*/-+&|\verb"|" and for every pair of types;
+%   \item |\__fp_|\meta{type_1}|_bcmp_|\meta{type_2}|:ww| for every
+%     pair of types.
+% \end{itemize}
+% The latter is set up in \pkg{l3fp-logic}.

+% \subsection{Storing simple tokens}
+%
+% It is sometimes necessary to store a list of \texttt{N}-type tokens in
+% a floating point array.  The structure we use is
+% \begin{quote}
+%   \cs{s_@@_tokens} \cs{@@_tokens:n} \Arg{\texttt{N}-type tokens} |;|
+% \end{quote}
+% This is not really a floating point datatype, since it cannot appear
+% directly within a floating point expression: there is thus no need to
+% define how the various floating point operators and functions act.  We
+% only need to be able to jump over the data with
+% \cs{@@_exp_after_tokens_f:nw}.
+%
+% \begin{variable}{\s_@@_tokens}
+%   Marks the start of some \texttt{N}-type tokens stored as a
+%   floating-point object.
+%    \begin{macrocode}
+\scan_new:N \s_@@_tokens
+%    \end{macrocode}
+% \end{variable}
+%
+% \begin{macro}[EXP]{\@@_tokens:n}
+%   To be used in combination with \cs{s_@@_tokens}: this function
+%   prevents the expansion of its argument.
+%    \begin{macrocode}
+\cs_new:Npn \@@_tokens:n #1 { \exp_not:n { \@@_tokens:n {#1} } }
+%    \end{macrocode}
+% \end{macro}
+%
+% \begin{macro}[EXP]{\@@_exp_after_tokens_f:nw}
+% \begin{macro}[EXP]{\@@_exp_after_tokens_aux:N}
+%   The loop through tokens ends when the auxiliary takes in the
+%   multi-token trailing argument.  The \cs{exp_after:wN} chain hits
+%   \cs{exp:w} coming from the argument, and
+%   \cs{use_none:nn} removes the looping macro.
+%    \begin{macrocode}
+\cs_new:Npn \@@_exp_after_tokens_f:nw
+    #1 \s_@@_tokens \@@_tokens:n #2 ;
+  {
+    \exp_after:wN \@@_exp_after_tokens_auxii:w
+    \exp:w
+    \@@_exp_after_tokens_aux:N #2
+      { \s_@@_tokens \exp:w \use_none:nn }
+    \exp_end_continue_f:w #1
+  }

+    \exp_after:wN \exp_end:

+  }
+\cs_new:Npn \@@_exp_after_tokens_auxii:w #1 \s_@@_tokens

-% \subsection{Support for types}
-%
-% Despite lack of documentation, the \pkg{l3fp} internals support types.
-% Each additional type must define
-% \begin{itemize}
-%   \item |\s__fp_|\meta{type} and |\__fp_|\meta{type}|_chk:w|;
-%   \item |\__fp_exp_after_|\meta{type}|_f:nw|;
-%   \item |\__fp_|\meta{type}|_to_|\meta{out}|:w| for \meta{out} among
-%     |decimal|, |scientific|, |tl|;
-% \end{itemize}
-% and may define
-% \begin{itemize}
-%   \item |\__fp_|\meta{type}|_to_int:w| and |\__fp_|\meta{type}|_to_dim:w|;
-%   \item |\__fp_|\meta{op}|_|\meta{type}|_o:w| for any of the \meta{op}
-%     that the type implements, among |acos|, |acsc|, |asec|, |asin|,
-%     |cos|, |cot|, |csc|, |exp|, |ln|, |not|, |sec|, |set_sign|, |sin|,
-%     |tan|;
-%   \item |\__fp_|\meta{type_1}|_|\meta{op}|_|\meta{type_2}|_o:ww| for
-%     \meta{op} among |^*/-+&|\verb"|" and for every pair of types;
-%   \item |\__fp_|\meta{type_1}|_bcmp_|\meta{type_2}|:ww| for every
-%     pair of types.
-% \end{itemize}
-% The latter is something added only by \pkg{l3fp-types} at present.

-% \subsection{Storing simple tokens}
-%
-% It is sometimes necessary to store a list of \texttt{N}-type tokens in
-% a floating point array.  The structure we use is
-% \begin{quote}
-%   \cs{s_@@_tokens} \cs{@@_tokens:n} \Arg{\texttt{N}-type tokens} |;|
-% \end{quote}
-% This is not really a floating point datatype, since it cannot appear
-% directly within a floating point expression: there is thus no need to
-% define how the various floating point operators and functions act.  We
-% only need to be able to jump over the data with
-% \cs{@@_exp_after_tokens_f:nw}.
-%
-% \begin{variable}{\s_@@_tokens}
-%   Marks the start of some \texttt{N}-type tokens stored as a
-%   floating-point object.
-%    \begin{macrocode}
-\scan_new:N \s_@@_tokens
-%    \end{macrocode}
-% \end{variable}
-%
-% \begin{macro}[EXP]{\@@_tokens:n}
-%   To be used in combination with \cs{s_@@_tokens}: this function
-%   prevents the expansion of its argument.
-%    \begin{macrocode}
-\cs_new:Npn \@@_tokens:n #1 { \exp_not:n { \@@_tokens:n {#1} } }
-%    \end{macrocode}
-% \end{macro}
-%
-% \begin{macro}[EXP]{\@@_exp_after_tokens_f:nw}
-% \begin{macro}[EXP]{\@@_exp_after_tokens_aux:N}
-%   The loop through tokens ends when the auxiliary takes in the
-%   multi-token trailing argument.  The \cs{exp_after:wN} chain hits
-%   \cs{exp:w} coming from the argument, and
-%   \cs{use_none:nn} removes the looping macro.
-%    \begin{macrocode}
-\cs_new:Npn \@@_exp_after_tokens_f:nw
-    #1 \s_@@_tokens \@@_tokens:n #2 ;
-  {
-    \exp_after:wN \@@_exp_after_tokens_auxii:w
-    \exp:w
-    \@@_exp_after_tokens_aux:N #2
-      { \s_@@_tokens \exp:w \use_none:nn }
-    \exp_end_continue_f:w #1
