p5.js char() function

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);
}

Output:
