Edit report at https://bugs.php.net/bug.php?id=74422&edit=1 ID: 74422 Updated by: requinix@php.net Reported by: jose dot carlos dot garcia dot 95 at gmail dot com -Summary: Round function sometimes return no float values +Summary: Round function returns false for non-numeric argument -Status: Open +Status: Analyzed Type: Bug Package: *Math Functions Operating System: Ubuntu PHP Version: 7.0Git-2017-04-12 (Git) Block user comment: N Private report: N New Comment: Typically built-in functions return NULL when given an argument of the wrong type, but returning false is also permitted. http://php.net/manual/en/functions.internal.php Looks like round RETURN_FALSEs for values that aren't int or float. It should be fine to change that, right?

Test script: --------------- <?php $valores = [ array(), array("test" => "hola") ]; foreach($valores as $valor) { echo var_dump(round($valor)); } Expected result: ---------------- A float value, or maybe a change in round function that reports when a type is invalid. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74422&edit=1
