I'm using PHP3 cvs version as of 17th feb.  This isn't really a bug IMO, but it's odd.

Using the code:-

<?
$Y2="6";
$Y1="5";
$MINYVALUE=0;
$SCALE=4;

echo "Y2=$Y2,Y1=$Y1,MINYVALUE=$MINYVALUE,SCALE=$SCALE<P>\n";

$dbg=($Y2+$Y1-$MINYVALUE)*$SCALE;

echo "dbg=$dbg<P>\n";
?>

---
result:-

Y2=6,Y1=5,MINYVALUE=0,SCALE=4

dbg=260


---

Yet (6+5-0)*4 = 44

Now, I know the code is wrong because I'm assigning string values to $Y1 and $Y2, but why does it not convert the values correctly?

I've now fixed my code by removing the quotes from around the numbers, and the calculation is then correct.

I suppose I don't want a bug fix so much as to know why an implicit string to number conversion didn't work.

Thanks!
