p5.js char() function

0 0 2 minutes read

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:
