This is my System:
You can convert a decimal number to a number system you want, like the binary system.
<?php
function Dec2oSys($numberDec, $SysNum)
{
if($numberDec != 0)
{
$numberOSys = "";
for (; $numberDec > 0;) {
$numberDecBefore = $numberDec;
$numberDec = $numberDec / $SysNum;
$pos = strpos($numberDec, '.');
if($pos != false)
{
$numberDec = floor($numberDec);
$numberOSys .= $numberDecBefore - floor($numberDec) * $SysNum;
$rest = $numberDecBefore - floor($numberDec) * $SysNum;
}
else
{
$numberOSys .= "0";
$rest = 0;
}
print $numberDec."; Rest:".$rest."<br/>";
}
}
else
{
$numberOSys = "0";
}
return strrev($numberOSys);
}
print Dec2oSys(100, 2);
?>
