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 valueslet binary1 = 0b1let binary2 = 0b11101let binary3 = 0b101010let binary4 = 0b111111// print binary values as decimalsprint(binary1); // 1print(binary2); // 29print(binary3); // 42print(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.
