How to select numbers with precision in oracle?

To select numbers with precision in Oracle, you can use the ROUND function to specify the number of decimal places you want to include in your result.

For example, if you have a column named "price" in a table named "products" and you want to select the price with only two decimal places, you can use the following query:

1
2

SELECT ROUND(price, 2) as rounded_price
FROM products;

This will round the "price" column values to two decimal places and display them as "rounded_price" in the result set.

You can also use the TO_NUMBER function to specify the precision and scale of a number. For example, if you want to select a number with a precision of 10 and a scale of 2, you can use the following query:

1
2

SELECT TO_NUMBER(price, '9999999999.99') as precise_price
FROM products;

This will format the "price" column values according to the specified precision and scale and display them as "precise_price" in the result set.

Overall, by using the ROUND function or the TO_NUMBER function with the appropriate format, you can select numbers with precision in Oracle.
