Integer Size Problem. Cuts off

[tsilenzio]

whenever I run this script the number never exceeds 253,000,000

 

If i change ethier one of these vairables

$startInvest

Or

$days

 

The script stops and displays results when $currInvest is greater then 253,000,000. How would i fix this so the script goes, I need the numbers to be as big as 1,000,000,000,000 about, bigger if possible

 

<?php
$percent[0] = 0.9;
$percent[1] = 1.0;
$percent[2] = 1.1;
$percent[3] = 1.2;
$percent[4] = 1.3;

$minrange[0] = 1000000;
$minrange[1] = 10000000;
$minrange[2] = 50000000;
$minrange[3] = 100000000;
$minrange[4] = 250000000;

$maxrange[0] = 9999999;
$maxrange[1] = 49999999;
$maxrange[2] = 99999999;
$maxrange[3] = 249999999;
$maxrange[4] = 0;

$startInvest = 10000000;
$weeklyDeposit = 500000;
$currInvest = $startInvest;
$days = 280;
$startPercent = 0;
$endPercent = 0;
$lastIncrease = 0;

// Loop thru all days
for($i = 1; $i < $days + 1; $i++) {
  if($i == 1) {
    echo("<table cellspacing=\"5\">\n<tr align=\"right\">\n<td><b>Day</b></td>");
    echo("\n<td align=\"center\"><b>Investment</b></td align=\"right\">\n<td><b>Percent</b></td>");
    echo("\n<td align=\"center\"><b>Daily Interest</b></td>\n");
    echo("\n<td align=\"center\"><b>Deposit Increase</b></td>\n</tr>");
  }

  // Test each array element
  for($j = 0; $j < count($percent); $j++) {

    // See where the current investment fits into
    if(($currInvest >= $minrange[$j]) && ($currInvest <= $maxrange[$j])) {
$lastIncrease = $currInvest;
      $currInvest *= (($percent[$j] / 100) + 1);
      $lastIncrease = $currInvest - $lastIncrease;

      echo("<tr><td align=\"right\">" . number_format($i) . "</td>\n");
      echo("<td align=\"right\">$" . number_format($currInvest) . "</td>\n");
      echo("<td  align=\"right\">" . number_format($percent[$j], 1) . "%</td>");
      echo("<td align=\"right\">$" . number_format($lastIncrease) . "</td>");

      if(($i % 7 == 0) && ($weeklyDeposit > 100000)) { 
        $currInvest += $weeklyDeposit;
        echo("<td align=\"right\">\$" . number_format($weeklyDeposit) . "</td></tr>");
      } else {
        echo("<td align=\"right\">$0</td></tr>");
      }
    }
  }

  if($i == $days) {
    echo("\n</tr>\n</table>");
  }
}
?>

this may help

see Integer overflow section

[tsilenzio]

So i would have to do var_dump($value); ?

it doesn't say that!

it basically says Integers over 2,147,483,647 become floats..

but reviewing your code in don't see any integer based problems!
