Hi guys, is there a function in php which makes it possible to extract the decimal part of a float number?
For example I've got : $x= 7.4 how do I get the decimal part? (that should return 0.4..) 🙂
Thanks!

    $x = 7.4;
$explode = explode('.', $x);
echo $explode[1];

      you're right! what a dumb question 😃

      Thanks!

          Yup, simple. Why didn't I think of this?:o

          However, before exploding it, I changed the integer to a dollar amount. That took care of the rounding. Here is what I did, in case somebody wants to know:

          function convert_number($number)
{
    if (($number < 0) || ($number > 999999999))
    {
        return "$number";
    }

$Gn = floor($number / 1000000);  /* Millions (giga) */
$number -= $Gn * 1000000;
$kn = floor($number / 1000);     /* Thousands (kilo) */
$number -= $kn * 1000;
$Hn = floor($number / 100);      /* Hundreds (hecto) */
$number -= $Hn * 100;
$Dn = floor($number / 10);       /* Tens (deca) */
$n = $number % 10;               /* Ones */

$res = "";

if ($Gn)
{
    $res .= convert_number($Gn) . " Million";
}

if ($kn)
{
    $res .= (empty($res) ? "" : " ") .
        convert_number($kn) . " Thousand";
}

if ($Hn)
{
    $res .= (empty($res) ? "" : " ") .
        convert_number($Hn) . " Hundred";
}

$ones = array("", "One", "Two", "Three", "Four", "Five", "Six",
    "Seven", "Eight", "Nine", "Ten", "Eleven", "Twelve", "Thirteen",
    "Fourteen", "Fifteen", "Sixteen", "Seventeen", "Eightteen",
    "Nineteen");
$tens = array("", "", "Twenty", "Thirty", "Fourty", "Fifty", "Sixty",
    "Seventy", "Eigthy", "Ninety");

if ($Dn || $n)
{
    if (!empty($res))
    {
//            $res .= " and ";
           $res .= " ";
        }

    if ($Dn < 2)
    {
        $res .= $ones[$Dn * 10 + $n];
    }
    else
    {
        $res .= $tens[$Dn];

        if ($n)
        {
            $res .= "-" . $ones[$n];
        }
    }
}

if (empty($res))
{
    $res = "zero";
}

return $res;
}

$USDollar = number_format($TotNet, 2,'.',','); // put it in decimal format, rounded

$printTotNet = convert_number($TotNet);  //convert to words (see function above)
$table .= '*********** ';
$x = $USDollar;
$explode = explode('.', $x);   //separate the cents
$printDolCents = $printTotNet . ' Dollars and ' . $explode[1] . ' Cents ***';
$table .= $printDolCents;  // print the line with dollars words and cents in numerals

          Thanks for your help
