How to convert a double to integer ?

Hi,how do convert an output of a pow(2,n) method of Math class to integer. Since this pow(x double, y bouble) gives an output of type double, how do i convert this output to integer if i want the value returned as an integer ?thanks aron

By casting (but note that this may not yield the results you want)...

class Test {

public static void main(String[] argv) {

double a = 5.5;

double b = 6.6;

int c = (int)(a + b);

System.out.println(c);

}

int value = Integer.parseInt(String.valueOf(Math.pow(2,3)));I'm sure others can make it uglier.

Could you please elaborately explain your statement. I am basically trying to understand the concept. What does valueOf(double y)do and why String class and why pasrInt()... please explain elaborately if you could thats great !! thanx

My reply was meant as a joke. Don't do it this way. See reply #1.

#1 is correct#5 is not sophisticated. It is convoluted as hell.oops ... I meant reply #3....Message was edited by: Navy_Coder

Reply #3 is not more sophisticated. In fact it is deliberately awful for humor purposes.

In other threads I have provided good advice of how to implement something and had it totally ignored. Here I deliberately provided bad advice and for some reason OP has zeroed in on it instead of the cleaner more sensible explanation. So now I know what I have to do in future in order to be "heard".

In all this hubbub, is it ok to mention the BigInteger pow method?

The shorter the answer, the more likely it is to be ignored AFAICS. The long-winded answers with all the crappy code seem to get all the attention.

That doesn't stop me trying to post minimalist answers, though. It's just the way I am.

I recall once a person asked if generics would be removed from JDK 1.6, and I said (sarcastically) that not only was that true, but also the letter "e" would be removed from the supported character sets. The OP of that thread believed me.

int i = (int)Math.pow(x, y);
