Just do not understand why the following two have different values. The first one has value 0, while the other has value 1
if(1/10);
if(0.1);

1do if(1/10.0) or if(1.0/10) or if(1.0/10.0) and it will give you 0.1 as division will be done with floating point values. – Tahlil Apr 07 '14 at 10:49

you can also use `1f/10` – Grijesh Chauhan Apr 07 '14 at 11:13

... or `1./10` or `1/10.`. – alk Apr 07 '14 at 11:33

By default the type of 1 is int, thus 1/10 will be rounded down to 0 which is equivalent to false. While 0.1 has some bits set and is not 0.
On the other hand 1.0/10 is equivalent to 0.1.

4I think it's good to note, that even `1.0/10` and `0.1` are not necessarely equal, because of floating point numbers representation features. – FreeNickname Apr 07 '14 at 10:48
0
if(condition)
Here the condition is executed and checked with 0. If that is 0 that means false else that means true. 1/10 gives value 0 which is equal to 0 ( as integer/integer gives integer result) so condition failes, where as 0.1 is not equal to 0, so it is treated as true and currespoinding statements in if block will be executed.
