How do you check if number is decimal or not PHP? The is_numeric() function checks whether a variable is a number or a numeric string. This function returns true (1) if the variable is a number or a numeric string, otherwise it returns false/nothing.
$percent = round((float)$str * 100 ) . '%';
Where $str = "0.274509817"
