[SOLVED] divide numbers strange results

[phpnewbie112]

Hello,

 

I have the following piece of code:

 

$out = "1.1";

$rate = "1.1";

$after =  $out/$rate;

print $after;  //Result is showing 1 normally

 

the problem is with the following wrong result

 

$a = "1";

$cnt = "1";

$b = (($out/$rate) - ($cnt * $a));

print $b;

 

the result is supposed to be 0 but I am having as a result:

1.11022302463E-15

 

very wierd!!!

[DarkWater]

$b = (round($out/$rate) - ($count * $a));

 

Try that.
