Parameters: This function accepts a parameter String which is a hexadecimal number and is to be converted into its integer equivalent value. This parameter might also be an array of strings of the hexadecimal numbers.
Return Value: It returns the converted integer representation.
Below program illustrates the unhex() function in p5.js.
Example-1:
function setup() { // Creating Canvas size createCanvas(500, 100); } function draw() { // Set the background color background(220); // Initializing some strings let String1 = "F"; let String2 = "FF"; // Calling to unhex() function. let A = unhex(String1); let B = unhex(String2); // Set the size of text textSize(16); // Set the text color fill(color('red')); // Getting integer equivalent text("Integer equivalent of hexadecimal string 'F' is: " + A, 50, 30); text("Integer equivalent of hexadecimal string 'FF' is: " + B, 50, 60); } |
Output:
Example-2:
function setup() { // Creating Canvas size createCanvas(650, 100); } function draw() { // Set the background color background(220); // Initializing some strings let String1 = ["F", "A", "C"]; let String2 = ["FF", "AC", "DE"]; // Calling to unhex() function. let A = unhex(String1); let B = unhex(String2); // Set the size of text textSize(16); // Set the text color fill(color('red')); // Getting integer equivalent text("Integer equivalent of array of hexadecimal strings"+ " ['F', 'A', 'C'] is: " + A, 50, 30); text("Integer equivalent of array of hexadecimal strings"+ " ['FF', 'AC', 'DE'] is: " + B, 50, 60); } |
Output:
