Usage of decimal in sql

The DECIMAL data type in SQL is used to store exact decimal numbers. It has the following syntax: DECIMAL(precision, scale), where precision is the total number of digits and scale is the number of digits after the decimal point. DECIMAL is used to store financial data, monetary values, and other numbers that require high precision. Unlike FLOAT and DOUBLE, DECIMAL stores exact values ​​without using scientific notation. It takes up more storage space than FLOAT or DOUBLE. You should use = and <> operators when comparing. If you need greater precision and range, you can use NUMER
