Hi,
Here is a question from Marcus
Which of the following are legal statements?
1) float f=1/3;
2) int i=1/3;
3) float f=1.01;
4) double d=999d;
The correct answer is 1,2,4.
I compiled & got it correct too.But i have a small doubt.When u say float f=1/3,why does'nt it consider 1/3 which 0.3333 as double.We know that the default type for decimal type is double.Why does'nt it give an error for No.2 option too?I have the same doubt here.Can anyone please make it clear for me?
Thanks

rubna,
I think it is considering 1/3 as integer division in both 1. and 2. The result integer 0 is assigned to float in case 1 and to int in case 2.

In case of 1, f = 1/3 is converted to 1.0f/3.0f
Thanks

i am afraid it is not true. try this:
<code>
float ff = 1/3;
System.out.println(ff);
float f=1.0f/3.0f;
System.out.println(f);
</code>

I believe Savithri is right.
In float f = 1/3; The right hand side is first caculated.
The result integer 0 is thenprompted as 0f and assigned
to the left hand side.

Hi,
I think Savuthiri is right . I executed this in JBuilder 2 and works out.
Michael: I too hope that Devaraj's statement is not true.
Thanks.
