phpmicrotime

php microtime() behaving differently

I'm working with an API which calculates a timestamp using the following function:

public function timestamp() {
  return round(microtime(TRUE) * 1000);
}

But when i call the function on my localhost and on my webhost, i get the following in return:

1.37872612307E+12

But if i get other people to run the same code on their server(and using http://writecodeonline.com/php/), i get the following, and correct timestamp back:

1378726142452

But why?

Running XAMPP on OSX, and on unoeuro.com webhost.

    You can set precision setting in php.ini file. It should be greater than yours(14)

    For ex my ini setting is 16:

    precision = 16
