evaluating decimal value

[Anon]

I have a column in a mysql table that is decimal(6,2). If a null value is stored in that column it gets stored as 0.00. If I print a variable with that value I get the following:

print($var); = 0.00

however the following conditional statement does not evaluate properly:

if($var!=0.00){
print("$var didn't equal 0.00");
}else{
print("$var did equal 0.00");
}

this always evaluates as the second option. Can someone explain what I am doing wrong here?

Any assistance is appreciated.

just for the hell of it, try this:

if (!$var) {
print("$var did equal 0.00");
} else {
print("$var didn't equal 0.00");

}

interesting, I will try that, I also just did this which seemed to work:

$varSub=explode(".", $var);
if($varSub[0]!=0){
...
}

right, but luckily that won't ever be the case with this particular application, but thanks for the heads up.
