== operator comparisons

[Guangcheng Zhou]

Hi all,

I was wondering why the following code is printing true and false.

double d1 = 2.5;
double d2 = 2.6;
System.out.println(d1 == 2.5f);
System.out.println(d2 == 2.6f);

Shouldn't they be printing the same boolean value at least?


Thanks,


Mack

try this..
double d1= 2.5f;
double d2= 2.6f;
System.out.println(d1);
System.out.println(d2);
.. now i think you've got answer!

I am still not getting this. Can any one explain why value of 2.6f is 2.5999999046325684 ???
