Decimal Number System
The base of the decimal number system is 10. In this number system, 10 digits are used - 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. We know that in decimal number system successive positions to the left of the decimal point represents units, tens, hundreds, etc. It is used in our day to day life.
Hexadecimal Number System
The base of the hexadecimal number system is 16. Hence, there are 16 symbols or digits in this system. The first ten digits are similar to that of decimal number system - 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The rest six digits are represented by the symbols A, B, C, D, E, and F, representing decimal numbers 10, 11, 12, 13, 14, and 15 respectively. The largest single digit is F (1 less than the base 16). Each digit in hexadecimal number system represents a power of the base (16). This number system is used to represent colors in HTML programming; FF0000 represents Red, 00FF00 represents Green, 0000FF represents Blue, etc.
How to convert Decimal to Hexadecimal
Let's understand the conversion by following these steps-
- Divide the decimal number by 16.
- Write the remainder from Step 1 as the rightmost digit (least significant digit) of the new hexadecimal number.
- Divide the quotient obtained from the previous division by 16.
- Write the remainder from step 3 as next digit (to the left) of the new hexadecimal number.
Continue to perform steps 3 and 4, until you get the value of quotient equal to zero.
The steps mentioned above will become clearer when we apply them in an example. Suppose we have a decimal number 427 that we want to convert into hexadecimal number.
Hence, 42710 = 1AB16
