Is there any difference between floor() and intval()? Though both returns the same results, is there any issue with regard to performance? Which of the two is faster? Which is the right php function to use if I just want to return the whole value only of a decimal?
The goal here is to display 1999.99 to 1999, omitting the decimal value and only return the whole number.
$num = 1999.99;
$formattedNum = number_format($num)."<br>";
echo intval($num) . ' intval' . '<br />';
echo floor($num) . ' floor';
The functions give different results with negative fractions.
echo floor(-0.1); // -1
echo intval(-0.1); // 0
