Today, there are many companies and small businesses popping up in the world. There are many people working in these industries or companies. Managing employee payment records has become an important task for employers.

Therefore, every large or small company needs a proper payroll management system. It is almost impossible for employers to manually maintain payroll records for each employee in large companies.

First let us understand the payroll management system.

Salary management system

A payroll management system is a software that enables companies to manage their employees' financial statements in an orderly and automated manner. It is used to manage employee wages, bonuses, health benefits, transportation allowances, deductions, etc. These software or websites simplify the tedious task of managing large amounts of data, thereby making payroll processing easier.

Steps to follow

Create a div container containing three input elements that contain information about the employee's name, daily salary, and number of days worked.
Design them to your liking.
Create a button that when clicked will execute the show_salary function. To achieve this, use the onclick() attribute.
Use JavaScript to create variables for storing input data. Create a function show_salary to display the employee's name and base salary.
The basic salary displayed is the product of the daily salary and the number of working days.
Use the .innerHTML method to display output inside a p element.

usage instructions

tofixed() method - This method is used to convert a number to a string with the specified number of decimal places. The number of decimal places is specified within parentheses.

If there are more decimal places in the number, zeros are added by default. Following is the syntax of tofixed() method -

variable.tofixed();
