# Why does Java print infinity?

Contents

In case of double/float division, the output is Infinity, the basic reason behind that it implements the floating point arithmetic algorithm which specifies a special values like “Not a number” OR “infinity” for “divided by zero cases” as per IEEE 754 standards.

## Why am I getting infinity Java?

When your operations leave the range of float, you DO get infinity as a result, by default. As you said, however, infinity usually begins with a zero division somewhere, or with a cyclic (or too large of a) operation. If you post a snippet of your code i can give you a hint on where it’s ‘unprotected’.

## Can you Use infinity in Java?

The Double class in Java supports infinity. You can implement positive infinity or negative infinity.

## How do you handle infinity in Java?

Example 1

1. public class FloatIsInfiniteExample1 {
2. public static void main(String[] args) {
3. float f1 = 578648.67f;
4. Float f2 = new Float(f1/0);
5. //isInfinite will return true for infinity values.
6. System.out.println(f2+” value for isInfinite() method is : ” +Float.isInfinite(f2));

## What is infinity Java?

+3. Double.POSITIVE_INFINITY is the infinity equivalent in Java and it represents a theoretical highest number. 1st January 2020, 3:43 PM.

## What happens if you divide by zero Java?

Dividing by zero is an operation that has no meaning in ordinary arithmetic and is, therefore, undefined. … According to the Java specification of the division operation, we can identify two different cases of division by zero: integers and floating-point numbers.

## What is negative infinity in Java Script?

The negative infinity in JavaScript is a constant value which is used to represent a value which is the lowest available. This means that no other number is lesser than this value. … Negative infinity results in 0 when divided by any other number. When divided by itself or positive infinity, negative infinity return NaN.

## What is an infinite loop in Java with example?

An infinite loop occurs when a condition always evaluates to true. Usually, this is an error. For example, you might have a loop that decrements until it reaches 0. public void sillyLoop( int i ) { while ( i != 0 ) { i– ; } }

## How do you know if a double is infinite?

There are two fields for infinity in the Double class: POSITIVE_INFINITY and NEGATIVE_INFINITY which you can check for. Note that integer division by zero would throw an ArithmeticException thus your line would have to be 4.0/0 , 4/0.0 or 4.0/0.0 since 4 and 0 are integers and thus result in integer math.

## How do you declare a variable as infinity in Java?

Though it is impossible for a computer to literally represent the value of infinity in memory, the Java “double” and “float” data-type reserves two slots in its address range that are understood by the computer to refer to positive and negative infinity.

## What is double in Java?

Java double is used to represent floating-point numbers. It uses 64 bits to store a variable value and has a range greater than float type.

## What does 0 mean in Java?

‘0’ is the char value of zero. When you write a string, you’re writing an array of ‘char’ datatypes which the compiler translates into ASCII values (which have a corresponding decimal number value).

## What causes NaN in Java?

“NaN” stands for “not a number”. “Nan” is produced if a floating point operation has some input parameters that cause the operation to produce some undefined result. For example, 0.0 divided by 0.0 is arithmetically undefined. Finding out the square root of a negative number too is undefined.

## What is the largest int in Java?

The int type in Java can be used to represent any whole number from -2147483648 to 2147483647. Why those numbers? Integers in Java are represented in 2’s complement binary and each integer gets 32 bits of space.
