Why this for is infinite

[hitmanben2]

i wrote this code:

for(double x = 0.0; x != 1.0; x += 0.1)
cout << x << endl;

it was suppose to output the value from 0 to 1 but instead i got infinite loop.

So why is that?

And how can i fix it?

I tried it on my compiler and it worked perfectly.
can you please put all the code here?

i am sorry guys i meant x != 1.0 not x <= 1.0 i fixed it now

It's because of rounding errors. You can't rely on floating point numbers to be exactly equal to a number.

double x = 0.1; would be 0.100...001, which is not equal to 0.1 but is slightly larger.

thanks Ikaron for the answer that helped.
