It is a number conversion calculator that is used to convert the values in decimal (base 10) to the binary codes (base 2). It uses a simple formula in performing the conversions. The Decimal number is commonly used by the general public and it is commonly referred to as the base 10 numbering system.

The binary system is only comprised of two base values 0 and 1. The modern machines can use these digits to solve problems related to computing because the two states use the transistor in the digital electronics. 0 and 1 are the primary digits that represent the two states.

The first procedure of using this calculator is to enter the decimal number in the blank text field. Click the ‘Convert' button to carry out the conversion. Your results will be indicated at the bottom platform of the calculator below the three controls. The decimal to binary converter allows you to determine the values of the binary number and the hexadecimal number.

For example;

Convert 79 to binary number;


Enter the value 79 in the blank text field and click the ‘Convert' button. The results will be displayed as;

Binary number: 1001111

Hex number: 4F

If you want to convert the decimal number to binary codes, divide the number by 2 and the binary digits can be retrieved from the remainders.

The other two active controls perform useful functions of the calculator. The ‘Reset' button is used to clear all the previous data from the calculator. It is the fastest way of adjusting the calculator when you have more values to be converted to the binary codes.

The ‘Swap' button is used to alternate the flow of calculations allowing you to perform the reverse calculations. You can only get accurate results depending on the decimal number you entered in the blank text field.
