java - for-loop, increment by double

Question

I want to use the for loop for my problem, not while. Is it possible to do the following?:

for(double i = 0; i < 10.0; i+0.25)

I want to add double values.

Answer 1

To prevent being bitten by artifacts of floating point arithmetic, you might want to use an integer loop variable and derive the floating point value you need inside your loop:

for (int n = 0; n <= 40; n++) {
    double i = 0.25 * n;
    // ...
}
