To apply padding on decimal values in Oracle, you can use the LPAD or RPAD function, which are used to pad a string value with a specified character or set of characters.To pad decimal values, you can first convert them to a string using the TO_CHAR function. For example, if you have a decimal value like 12.34, you can convert it to a string using TO_CHAR(12.34).Then, you can use the LPAD or RPAD function to pad the string with zeros or any other character to a specified length.
