The char() function in p5.js is used to convert the given string or number value into its corresponding single-character string representation. If the input parameter is a string value then at first it gets converted into its integer equivalent internally after that its single-character string is represented as output and when an array of strings or number is taken as the parameter then it gives output as an individual single-character strings for each element of the array.
Syntax:
char( value )
Parameters: This function accepts single parameter value which is to be converted into its single-character string representation. This value might be a number, string of numbers and an array of strings or numbers.
Return Value: It returns the converted single-character string representation.
Below programs illustrate the char() function in p5.js:
Example 1: This example uses char() function to convert input value into its corresponding character.
function setup() {        // Creating Canvas size     createCanvas(600, 230); }    function draw() {            // Set the background color     background(220);          // Initializing some values     let Value1 = 66;     let Value2 = 67;     let Value3 = "65";     let Value4 = 62;     let Value5 = "62";     let Value6 = 90;          // Calling to char() function.     let A = char(Value1);     let B = char(Value2);     let C = char(Value3);     let D = char(Value4);     let E = char(Value5);     let F = char(Value6);            // Set the size of text     textSize(16);            // Set the text color     fill(color('red'));          // Getting character representation     text("Character representation of value 66 is: " + A, 50, 30);     text("Character representation of value 67 is: " + B, 50, 60);     text("Character representation of string '65' is: " + C, 50, 90);     text("Character representation of value 62 is: " + D, 50, 110);     text("Character representation of string '62' is: " + E, 50, 140);     text("Character representation of value 90 is: " + F, 50, 170); } |
Output:
Example 2: This example uses char() function to convert input value into its corresponding character.
function setup() {        // Creating Canvas size     createCanvas(600, 140); }    function draw() {            // Set the background color     background(220);          // Initializing some values     let Value1 = [66, 67];     let Value2 = ["66", "67"];     let Value3 = ["66", "67", "90"]          // Calling to char() function.     let A = char(Value1);     let B = char(Value2);     let C = char(Value3);            // Set the size of text     textSize(16);            // Set the text color     fill(color('red'));          // Getting character representation     text("Character representation of array [66, 67] is: " + A, 50, 30);     text("Character representation of array ['66', '67'] is: " + B, 50, 60);     text("Character representation of array ['66', '67', '90'] is: " + C, 50, 90); }     |
