Line 135:

The '' '''Conway box function''' '' section says ''See also: '''Sawtooth wave''''', but neither mentions the other one. What is the connection? How reading about ''Sawtooth wave'' allows better or deeper understanding of a ''boxed question mark'' function? --[[User:CiaPan|CiaPan]] ([[User talk:CiaPan|talk]]) 10:22, 22 April 2015 (UTC)

== A box ==

I could not find a single LaTeX command for a box to surround a given expression, however discovered a quite simple way do make a box with an array:

:: <tt>\begin{array}{|c|} \hline EXPR \\ \hline \end{array}</tt>

Result:

:: <math>\begin{array}{|c|} \hline EXPR \\ \hline \end{array}</math>

The <tt>{|c}}<tt> part declares a single column in the array with centered contents and vertical lines on both sides. Commands <tt>\hline</tt> add horizontal lines above and below the (single) row. Command <tt>\\</tt> terminates the row so that the bottom line can be drawn. <br/> Happy editing, everybody! :) [[User:CiaPan|CiaPan]] ([[User talk:CiaPan|talk]]) 10:50, 22 April 2015 (UTC)
