help on this...

i have this statement

pi = 4*(1-(1/3))

then i print it out.. pi is a double set to 0..

but it keeps printing out 4.0

instead of 2.6666666667 :( help

You're using ints to do double calculations. With integers, 1/3 is 0. 1-0 is 1. 4 * 1 is 4, so you get 4.0.

To see this better, do it in a few steps:

Code :

---

int step1 = 1/3;
System.out.println(step1);
int step2 = 1 - step1;
System.out.println(step2);
int step3 = 4 * step2;
System.out.println(step3);

---

so do i just create a double variable like

double tmp = 0.3;

to use 1/3?

uhh ok nevermind i got it thanks :)
