Thank Richard.
So far, I just punted. My site runs on a dedicated box and doesn't
have to service a lot of users so I just wrote a one line C program
to print a single value using a specified format (default is %.4e)
and use exec() to call it.
printe [format] value
Here's how I encapsulated it:
function printe( $x )
{
$lines = array();
exec( "/usr/local/bin/printe \"".$x."\"", $lines );
return $lines[0];
}
and an example of how I call the function:
fputs( $fp, sprintf( "%8.2f %s %s\n", $this->O_a_time[$i],
printe($this->O_a_height[$i]),
printe($this->O_a_cooling[$i]) ) );
It works well enough for now. Eventually I hope to have time to play
and then I'll come back and figure out a real patch for PHP's printf
to support %e directly.
