How to create a binary and print the value in decimal in Swift

Overview

We can create a constant in Swift using the let keyword. It is also easy to create an octal binary number, that is a number in base 2. All we need to achieve this is to place the 0b before the binary digits.

Syntax

let constant = 0b(binary_digit)
The syntax for creating a constant with binary as value

Parameters

  • let: This is the keyword used in creating a constant in swift.
  • constant: This is the name of the variable we want to create as a constant.
  • 0b : This is the keyword used to express a binary value.
  • binary_digit : This represents the binary digit or digits.

Return value

The value returned is a binary value.

Example

// create some binary values

let binary1 = 0b1

let binary2 = 0b11101

let binary3 = 0b101010

let binary4 = 0b111111



// print binary values as decimals

print(binary1);  // 1

print(binary2);  // 29

print(binary3);  // 42

print(binary4);  // 63

Explanation

  • Lines 2-5: We create some constant binary variables and assign them binary values using the 0b.
  • Lines 8-11: We print the binary values, in the form of decimals, to the console.
