Two Quick Java Questions

1: Is there a way to round to two decimal places without having to multiply by 100, Math.round, and then divide by 100?

2: If a value ends in .0, how can I have the program remove that from it?
 
1) Sure there is...no idea what, API has it!
2) if(value %1 == 0)
int tempValue = value;

I have no idea if that works but it seems pretty clever to me!
 
Ok, when I try that it doesn't really do anything because since 10.0 is a double and an int would be 10, they will never be the same. Heres the code:

intIncome = (int)varIncome;
if ((varIncome == intIncome);
{
varIncome = intIncome;
}

What am I doing wrong? Sorry if I sound like an idiot, but I'm new to Java
 
<---does not like Java, but will give it a shot

1. There is an API for it.

2.Assuming you already have a main

void SomeMethodName{

if (this.value%1!=0)
this.value=null;
else
this.value=this.value;<----can you do this?
}

keep in mind that io have no idea what your variables are.

edit: my bad, this should be a method, not a class.
 
just cheat, instead of doing this.value=this.value (not sure if you can do that), juts have it output something like "computed". That way the value will not change.

Can't you just do a parseInt(var)?

It's been a while since I took a java class...

That just makes it an int, but when the if statement sees if they are the same or not, to it 1.0 and 1 are not the same.

umm.... how about no
 
Just curious, why are you worrying about the format of the variable itself? I say leave the variable a float and only worry about formatting when you're actually displaying it.

float val = 1.0F;

if (val % 1 == 0) System.out.println((int)val);
else System.out.println(val);
