Description:
------------
---
From manual page: http://www.php.net/function.sqrt#refsect1-function.sqrt-returnvalues
---


Why didn't you say that sqrt() always return float, even if argument is, for example 4, 9, 16


Test script:
---------------
if (is_int(sqrt(9))) {
  echo 'true';
} else {
  echo 'false';
}



Expected result:
----------------
Expected value: true :)
