 Produce a mathematical array.  This environment can only be used in math
 mode, and normally appears within a displayed mathematics environment

+such as @code{equation} (@pxref{equation}).  Column entries are
+separated by an ampersand at domain.hid{&}.  Rows are terminated with
+double-backslashes at domain.hid{\\}.  The required argument @var{cols}
+describes the number of columns, their alignment, and the formatting of
+the intercolumn regions.
 
 The @code{array} environment is just like the @code{tabular}
-environment, except that entries are typeset in mathematics mode (as
- at domain.hid}, not @code{\displaystyle}).  
-
-There are two exception to this.  The first is that entries are not
-typeset in math mode if the column is specified with @code{@@p@{..@}} in
-the @var{cols} definition.  The second is that, instead of @code{tabular}'s @code{\tabcolsep}, @LaTeX{}'s intercolumn
-space in an array is governed by the parameter
+environment but entries are typeset in mathematics mode, in textstyle
+(except if the @var{cols} definition specifies the column with
+ at code{@@p@{..@}}, which causes the entry to be typeset in text mode).
+See @ref{tabular} for the complete description of @var{cols}, and of the
+other common features of the two environments.
+
+There are two ways that @code{array} diverges from @code{tabular}.  The
+first is that @code{array} does not have @code{tabular}'s argument
+ at var{pos} giving vertical alignment.  The second is that, instead of
+ at code{tabular}'s @code{\tabcolsep}, @LaTeX{}'s intercolumn space in an
+array is governed by the parameter
 @findex \arraycolsep
 @code{\arraycolsep} which gives half the width between columns; the
-default is @samp{5pt}.
-
-See @ref{tabular} for the complete description of @var{cols}, and of the

+default for this is @samp{5pt}.
 
 To obtain arrays with braces the standard is to use the @file{amsmath}
 package.  It comes with environments @code{pmatrix} for an array
