I'm posting this here because I dont know if it's a bug (I didn't find anything on the DB, or didn't know the right keyword to put) or if it's my mistake.

if I increase the value of a float number like 0. with a float number with two decimals like 0.01 (no problem with 0.1), the results don't seem exact.

i made a simple example to illustrate:

Code:

float value = 0;

void setup() {
  framerate(20);
}

void draw() {
  value = value + 0.01;
  println(value);
}

 

the output is:

0.01
0.02
0.03
0.04
0.049999997
0.059999995
0.06999999
0.07999999
0.08999999

and so on... the results aren't as they should be. with other numbers, like 0.05, the results start to mess up sooner. is this a bug or am I missing something?

Im using P93 on mac os x 10.3.9.

thanks for the quickness in replying!

The explanations are a bit too complex for me though. But what I understood is that this is a java problem, and the workaround to it is by using integers and then dividing them as needed.
