## How do you find the infinity number in Java?

**If you divide a number by zero, and the sign of both numbers is** the same, the result is positive infinity. 0.0 divided by 0.0 is positive infinity, as is -34.0 divided by -0.0 .

…

Division by zero.

Constant | Meaning |
---|---|

NEGATIVE_INFINITY | Negative infinity |

NaN | Not a number |

## Is infinity a number Java?

11 Answers. note: Infinity – **Infinity is Not A Number**.

## 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 happens if we divide by 0 in 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 the meaning of 1 0?

In mathematics, expressions like **1/0 are undefined**. But the limit of the expression 1/x as x tends to zero is infinity. Similarly, expressions like 0/0 are undefined. … Thus 1/0 is not infinity and 0/0 is not indeterminate, since division by zero is not defined.

## What is infinity in code?

As ironic as it may seem infinity is defined as **an undefined number that can either be a positive or negative value**. … In the world of computer science, infinity is generally used to measure performance and optimize algorithms that perform computations on a large scale application.

## What does infinity mean in Java?

JasvX. 2 Answers. +3. Double.**POSITIVE_INFINITY** is the infinity equivalent in Java and it represents a theoretical highest number.

## Can Java long be negative?

The reason why Java doesn’t throw an exception and you receive negative numbers has **to do with the way numbers are stored**. For a long primitive the first byte is used for indicating the sign of the number (0 -> positive, 1 -> negative), while the rest are used for the numeric value. This means that Long.

## What is the output of 1 0 in Java?

To answer the question, yes it is legal in Java, but 1/0 resolves **to “infinity”** and is treated differently from standard Doubles (or floats, or so on and so forth).

## Should I use float or double Java?

You should **use double instead of float for precise** calculations, and float instead of double when using less accurate calculations. Float contains only decimal numbers, but double contains an IEEE754 double-precision floating point number, making it easier to contain and computate numbers more accurately.

## Is double the same as float?

**Double is more precise than float** and can store 64 bits, double of the number of bits float can store. Double is more precise and for storing large numbers, we prefer double over float. … Unless we do need precision up to 15 or 16 decimal points, we can stick to float in most applications, as double is more expensive.

## Which is bigger double or long Java?

The main difference between long and **double** in Java is that long is a data type that stores 64 bit two’s complement integer while double is a data type that stores double prevision 64 bit IEEE 754 floating point. … In Java, both these data types require 8 bytes to store data.
