If you don't understand feel free to ask questions.

Answer 1

You could multiply by 100 and use Math.floor(double) like

int y = (int) Math.floor(x * 100);
System.out.println(y);

I get (the requested)

36

Note that if you use float, then you would get 36.0.

Answer 2

You could multiply x by 100 and use int instead of float. I tried the below code:

double x = 0.36843871;
int y = (int)(x*100);
System.out.println(y);

And got output as:

36
