In this program, you'll learn to convert decimal to binary, octal and hexadecimal, and display it.

To understand this example, you should have the knowledge of following Python programming topics:

Decimal system is the most widely used number system. But computer only understands binary. Binary, octal and hexadecimal number systems are closely related and we may require to convert decimal into these systems. Decimal system is base 10 (ten symbols, 0-9, are used to represent a number) and similarly, binary is base 2, octal is base 8 and hexadecimal is base 16.

A number with the prefix '0b' is considered binary, '0o' is considered octal and '0x' as hexadecimal. For example:

60 = 0b11100 = 0o74 = 0x3c

# Python program to convert decimal number into binary, octal and hexadecimal number system # Change this line for a different result dec = 344 print("The decimal value of",dec,"is:") print(bin(dec),"in binary.") print(oct(dec),"in octal.") print(hex(dec),"in hexadecimal.")

**Output**

The decimal value of 344 is: 0b101011000 in binary. 0o530 in octal. 0x158 in hexadecimal.

**Note:** To test the program, change the value of dec in the program.

In this program, we have used built-in functions `bin()`

, `oct()`

and `hex()`

to convert the given decimal number into respective number systems.

These functions take an integer (in decimal) and return a string.
