## How many numeric data types are there?

## How many numeric data types are there?

There are two categories of numeric data types: exact and approximate. Exact data types include integer data types and decimal data types.

## How many data types does Java handle real number data?

Real numbers in Java are represented with the float and double data types. As shown in Table 2-3, float is a 32-bit, single-precision floating-point value, and double is a 64-bit, double-precision floating-point value.

**What are the 5 data types in Java?**

Data types in Java

- Primitive Data Type: such as boolean, char, int, short, byte, long, float, and double.
- Non-Primitive Data Type or Object Data type: such as String, Array, etc.

**What are the numeric types?**

The exact numeric types are INTEGER , BIGINT , DECIMAL , NUMERIC , NUMBER , and MONEY . Approximate numeric types, values where the precision needs to be preserved and the scale can be floating. The approximate numeric types are DOUBLE PRECISION , FLOAT , and REAL .

### Which is not numeric data types in Java?

Java offers two additional non-numeric primitive data types: char (to represent alphanumeric characters and special symbols) and boolean (to represent the truth values true and false).

### What are the two types of numerical data?

Numerical data can take 2 different forms, namely; discrete data, which represents countable items and continuous data, which represents data measurement. The continuous type of numerical data is further sub-divided into interval and ratio data, which is known to be used for measuring items.

**What is the largest numerical type in Java?**

long

The largest integer number that a long type can represent is 9223372036854775807. If we deal with even larger numbers, we have to use the java….Integers.

Type | Size | Range |
---|---|---|

long | 64 bits | -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |

**What are the types of data types in Java?**

Data types are divided into two groups:

- Primitive data types – includes byte , short , int , long , float , double , boolean and char.
- Non-primitive data types – such as String , Arrays and Classes (you will learn more about these in a later chapter)

#### What are the four types of Java?

There are four platforms of the Java programming language:

- Java Platform, Standard Edition (Java SE)
- Java Platform, Enterprise Edition (Java EE)
- Java Platform, Micro Edition (Java ME)
- JavaFX.

#### Which is not numeric data type?

These are data that can’t be manipulated by arithmetic operators. They comprise of Text, String, Date, etc.

**What are the four non numeric built in types in Java?**

These are int, long, short, byte, float, and double, and they allow us to represent integer and real numbers. Java offers two additional non-numeric primitive data types: char (to represent alphanumeric characters and special symbols) and boolean (to represent the truth values true and false).
