echo($a[5]); //this is not printing 0 why?
for($x=-2;$x<2.1;$x+=0.4){
$a[] = $x*$x;
}
Output is:
Array
(
[0] => 4
[1] => 2.56
[2] => 1.44
[3] => 0.64
[4] => 0.16
[5] => 1.2325951644078E-32
[6] => 0.16
[7] => 0.64
[8] => 1.44
[9] => 2.56
[10] => 4
)
You can use number_format() or round() to get 2 decimal places, and that'll correct the value to 0.0. If you use number_format, you'll need to convert it to a float. Using round will work (tested), but if precision here is key, then round may not be best suited.
The world of using doubles/floats sucks sometimes :/
Thanks. That solved it
