I was attempting to find if the result of a calculation returned a number with any decimals.

So, I was doing something like:

```
$num=123.1/0.1;
if(floor($num)!=$num){
echo "has decimals";
}else{
echo "doesn't have decimals";
}
//has decimals
```

To my surprise the code above returns: *‘has decimals’*

If you do the math in any calculator the result of *123.1/0.1=1231* and in fact that is what PHP displays when you do:

```
echo 123.1/0.1;
//1231
```

But internally PHP stores the value in float and when you do:

```
echo floor(123.1/0.1);
//1230
```

As I only need to know if the number has any decimals, I ended up doing:

```
$num=round(123.1/0.1,1);
if(floor($num)!=$num){
echo "has decimals";
}else{
echo "doesn't have decimals";
}
```

I completely understand why Steve Wozniak never got round to add floating point support on BASIC, no sane person wants to deal with floating points.
