Problems in a Double expression

I would appreciate if anyone could help with an issue i've got :

Let's assume the following :

iOpen(Symbol(),0,1) == 231.11
Bid == 231.10

Therefore :

(iOpen(Symbol(),0,1) - Bid) should equal 0.01

When I try to make this expression :

if ((iOpen(Symbol(),0,1) - Bid) == Point) Alert ("Equal");

I don't get the alert.

The only things that make this work is if I write it like this :

if (NormalizeDouble( (iOpen(Symbol(),0,1) - Bid), Digits) == Point)
Alert ("Equal");

What I am assuming is when I deduct the open price from the bid, I'm probably getting a double which is presented as 0.0100000000000, while Point equals 0.01

In MQL4 does 0.01 not equal 0.010000000000

Do i have to normalize the expression before trying to check if equal ?
