[NXC] floor function not working!!!!

[nxtboyiii]

what round() function???
And I am using floor because I want it to round to the floor! Not just to nearest integer, but to floor because,lets say, 0.75 has to be 0, not 1, and the floor of 0.75 is 0, not 1.

it's because you wrote something about "rounding", not about fractional cut. The term "rounding" means always up or down to the nearest integer, "floor" doesn't round but cuts off the frac part.

EDIT: Is there a round function?(round to the nearest tenth, hundredth,etc)
If not, can someone show me how?

I think it was simply a misunderstanding of what you actually want or need.

[nxtboyiii]

Yes. About that. I asked for a round function so when I use floor I can round the integer to the nearest tenth because of floating-point arithmetics.

and do you want to round the float or truncate to 1 decimal fixed point and cut off the rest?
1.111 => 1.1 (is trivial)
but:
8.888 => 8.8 or 8.9?

[nxtboyiii]

I want to round I guess.

I got it to work!!
I just did what linusa said:

Code: Select all

int xx;
float yy;

xx++;
yy=xx/10;

It didn't get messed up!!
Thanks doc-helmut and linusa!
