Closing as scientific notation is already available via %e, %E (and %g, %G for
mixed).

I humbly request that scientific notation formatting (ex. 7.16e-11) is added to
the function sprintf(). Currently I am using a function supplied by another
user:
function sci($x, $d=-1) {
$e=floor(log10($x));
$x*=pow(10,-$e);
$fmt=($d>=0)?".".$d:"";
$e=($e>=0)?"+".sprintf("%02d",$e):"-".sprintf("%02d",-$e);
return sprintf("%".$fmt."fe%s",$x,$e);
}
and can be found in the comments of this page:
http://www.php.net/manual/en/function.sprintf.php
This function seems to be working fine for the time being, but this seems like
somethine many other people would use and an addition to PHP itself would be
better.
