Strange comportment ...

Hi,

I got a function that do a very strange calculation ... Here is the code
fragment


function ChiffreEnLettre($chiffre)
{

$centaine = 0;
$dizaine = 0;
$unite = 0;
$reste = 0;
$y = 0;
$dix = false;
$lettre = "";
$reste = $chiffre;

// print(" Valeur recue = $reste<br>");

for( $i = 1000000000; $i >= 1; $i = $i / 1000)
{
$y = (int) ($reste / $i);
print("$y = $reste / $i ");

....
....


When i call this function many time with different number i got strange
values for the $y var.

Sometime when i call the function with $chiffre = 5, I got got $y = 5 ,
and other time i got $y = 4 !!!! I also got the same strange comportment
when I call the function with $chiffre = 45, sometime i got $y = 45 and
dometime i got $y = 44 ...

This problem only occur when $i = 1. So in this case, for PHP, 5 / 1 = 4
!!!

if i replace $y = (int)($reste / $i); by $y = ($reste / $i); evrything
is ok, so it appear that it's the casting that is transforming the 5 value
in the 4 value.

If anybody has an explication,

Best regards,

Alain Deseine.
