How to round in oracle

The ROUND function can be used in Oracle to perform rounding operations. The basic syntax of the ROUND function is "ROUND(number, decimal_places)". Among them, number is the number to be rounded, and decimal_places is the number of decimal places to be retained.

In Oracle, you can use the ROUND function to perform rounding operations. The basic syntax of the ROUND function is as follows:

ROUND(number, decimal_places)

Among them, number is the number to be rounded, and decimal_places is the number of decimal places to be retained. If decimal_places is a positive number, the ROUND function rounds the number to the specified number of decimal places; if decimal_places is negative, the ROUND function rounds the number to the specified number of decimal places to the left of the decimal point.

For example, to round a number to two decimal places, you can use the following SQL statement:

SELECT ROUND(123.456, 2) FROM dual;

This will return the result 123.46.

In addition to the ROUND function, Oracle also provides the CEIL and FLOOR functions, which are used for rounding up and rounding down respectively. These functions can perform numerical rounding operations according to specific needs.
