Some bug (may be) in Array.indexOf

Hi @Gordon,

While trying to do some statistics, I found that situation on a v2.00 upgrade Pico:

>var tab1mAlpha = new Array( 0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999);
=[ 0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999 ]
>console.log(tab1mAlpha.indexOf(v))
-1
=undefined
>v
=0.95
>typeof v
="number"

However, using the test box in the mozilla page, I got

var tab1mAlpha= [0.05, 0.1, 0.2, 0.3, 0.5, 0.7, 0.8, 0.9, 0.95, 0.99, 0.999];
var v=1-0.05;
console.log(tab1mAlpha.indexOf(v));
console.log(typeof v);

which once run showed:

> 8
> "number"

So, is this a bug or I am not understanding something?

P.S.: Should I report this type of problem on the forum or in github?
