err..... I dunno.....

(edited)

wrong:

it's because it's int - it gets rounded

try

1. float val = 10/4;
2. println(val);

1. float val = 10.0/4.0;
2. println(val);

Two things:

1. The variable var must be a float if you want to store a decimal number.
2. 10/4 is an integer division which means it ignores the remainder after division.

ah, I think you need to write 10.0 to make sure it's float and not int

1. println("normal / div --------------------");
2. float val ;
3. // println(nf(val, 1, 3));
4. val = 10.0 / 4;
5. println(nf(val, 1, 3));
6. println("now via PVector---------------------");
7. PVector v;
8. v = new PVector(10, 0, 0);
9. println(v.x);
10. // div
11. v.div(4);
12. println(v.x);

See the Troubleshooting Wiki Article, particular ly the part titled " Why does 2 / 5 = 0 instead of 0.4"...

yeah thank you again..

2 / 5 = 0

2.0 / 5 or 2 / 5.0 = 0.4

perfect..
