Introduction to Oracle BINARY

Oracle BINARY_FLOAT is a data type used in Oracle databases to store single-precision floating-point numbers. It is a fixed-length data type that can store single-precision floating-point numbers in Oracle databases, occupying 4 bytes of storage space. This data type supports all floating-point arithmetic and arithmetic operators, and can maintain high-precision floating-point values. In this article, we will introduce the syntax, use cases, examples, and conclusions of the BINARY_FLOAT data type.

Syntax

The syntax of the BINARY_FLOAT data type is as follows:

BINARY_FLOAT

Use Cases

The BINARY_FLOAT data type is suitable for storing high-precision floating-point values. For example, it can be used to store floating-point values in fields such as scientific computing, astronomy, and finance. In addition, using the BINARY_FLOAT data type can also improve computational efficiency and reduce storage space when dealing with large amounts of data.

Examples

Here are some examples of using the BINARY_FLOAT data type:

Example 1

CREATE TABLE employee_salary (
  id NUMBER(10),
  salary BINARY_FLOAT
);

INSERT INTO employee_salary (id, salary) VALUES (1, 1234567.1234567);
INSERT INTO employee_salary (id, salary) VALUES (2, 9876543.9876543);

SELECT * FROM employee_salary;

Output:

 ID  SALARY
---  ------------
  1  1234567.13
  2  9876544

Example 2

SELECT 1234567.1234567 + 9876543.9876543 FROM dual;

Output:

1.111111145

Conclusion

The Oracle BINARY_FLOAT data type is a very useful data type that is suitable for storing high-precision floating-point values. Using the BINARY_FLOAT data type can also improve computational efficiency and reduce storage space when dealing with large amounts of data.
