Remove useless zero from scientific notation in PHP

Question

Is there any way to Remove useless zero from scientific notation and make the number as simple as possible.

In PHP I have the following code:

<?PHP
  $result = 1/1000000000;
  echo $result;
?>

the output is 1.0E-9

it should 1E-9

Answer 1

If you need it this way you can use str_replace :

$result = 1/1000000000;
echo str_replace(".0E", "E", $result);

This outputs 1E-9
