{title:Description}

{p 4 4 2}
{cmd:strofreal(}{it:R}{cmd:)} returns {it:R} as a string using
Stata's {cmd:%9.0g} format.
{cmd:strofreal(}{it:R}{cmd:)} 
is equivalent to {cmd:strofreal(}{it:R}{cmd:, "%9.0g")}.

{p 4 4 2}
{cmd:strofreal(}{it:R}{cmd:,} {it:format}{cmd:)} returns {it:R} as a
string formatted using {it:format}.

               {it:R}:  {it:r1 x c1}
          {it:format}:  {it:r2 x c2}, {it:R} and {it:format} r-conformable
          {it:result}:  max({it:r1},{it:r2}) {it:x} max({it:c1},{it:c2})
