% BeginPlugInDocuSection
% PlugInDocuCaption: Convert to long
% PlugInName: to_long
% PlugInAuthor: Percy Zahl
% PlugInAuthorEmail: zahl@users.sf.net
% PlugInMenuPath: Math/Convert/to long

% PlugInDescription
Convert scan data type to long.

% PlugInUsage
Call \GxsmMenu{Math/Convert/to long}.

% OptPlugInSources
The active channel is used as data source.

% OptPlugInDest
The conversion result is placed into an existing math channel, else
into a new created math channel.

% OptPlugInNote
Conversion from higher to lower dynamic range type may result in
overflow, e.g. value wrapping round. There is no saturation mode yet.
