Double returning as zero?

Code:

    public double blindPercent(int magnitude){
        double percent = 0;
        plugin.getLogger().info(magnitude + "---ggg");
        percent = (magnitude/15);
        plugin.getLogger().info(percent + "---");
        return percent;
    }

In the above method, I'm trying to create a double, however for some reason it always returns as "0.0"

Magnitude is not null, and infact equals 1 (as illustrated by the plugin.getLogger()).

Why does this always return as 0.0?

 

Try changing magnitude to a double instead of an int, and cast double to the denominator.

Double/Integer division will always use the lowest precision result, in this case you will just receive an integer result.

You need to make sure all your variables are doubles or floats. This should fix your code.

Code:

 public double blindPercent(int magnitude){
        double percent = 0;
        plugin.getLogger().info(magnitude + "---ggg");
        percent = ((double)magnitude/15D);
        plugin.getLogger().info(percent + "---");
        return percent;
    }

I'd also recommend using a decimal formatter otherwise you will have a percentage with a lot of trailing numbers. Have a Google and give it a shot, it's a pretty useful class .
