Double in for loop

Question

Hello guys

I am loving the lessons so far. I got a quick question.

can i use double variables while running a for loop? I noticed only Int was used through the lessons.

example

for(double x=1.3; x<= 22.8; x++){
System.out,println(x);
}

thank you.

Answer 2

Floating type value is uncertain, in that they have fractal part. So verifying a variable value equals another variable/value can be tricky. Other than that, integers operation requires less CPU cycle (read: faster) compared to floating point types operation.

Answer 3

Practically you can, but I'm not sure it has any meaningful uses, plus it can be hard to determine how many times will it get executed
