p5.js | int() function
  • Last Updated : 11 Feb, 2021

The int() function in p5.js is used to convert the given boolean, integer, and float value into its integer representation.

Syntax: 

int(ns)

or 

int(n, radix)

Parameters: This function accepts three types of the parameter which are listed below: 

  • n: It stores the value which needs to converts into integer. The possible value of n is string, boolean, or number.
  • radix: It stores the radix part to which the number is converted.
  • ns: It stores different types of elements into the array.

Return Value: It returns the converted integer representation.
Below programs illustrate the int() function in p5.js:
Example 1: This example uses int() function to convert input value into its integer value. 
 



javascript




function setup() {
  
    // Creating Canvas size
    createCanvas(600, 160);
}
  
function draw() {
      
    // Set the background color
    background(220);
    
    // Initializing some strings
    let Value1 = 12;
    let Value2 = 12.5;
    let Value3 = -7.9;
    let Value4 = -6;
    let Value5 = "6";
    
    // Calling to int() function.
    let A = int(Value1);
    let B = int(Value2);
    let C = int(Value3);
    let D = int(Value4);
    let E = int(Value5);
      
    // Set the size of text
    textSize(16);
      
    // Set the text color
    fill(color('red'));
    
    // Getting integer representation
    text("Integer representation of value 12 is: " + A, 50, 30);
    text("Integer representation of value 12.5 is: " + B, 50, 60);
    text("Integer representation of value -7.9 is: " + C, 50, 90);
    text("Integer representation of value -6 is: " + D, 50, 110);
    text("Integer representation of string '6' is: " + E, 50, 140);

Output: 
 

Example 2: This example uses int() function to convert input value into its integer value. 
 

javascript




function setup() {
  
    // Creating Canvas size
    createCanvas(600, 140);
}
  
function draw() {
      
    // Set the background color
    background(220);
    
    // Initializing some values
    let Value1 = true;
    let Value2 = false;
    let Value3 = "Geeks";
    let Value4 = [12, 3.6, -9.8, true, false, "Geeks"];
    
    // Calling to int() function.
    let A = int(Value1);
    let B = int(Value2);
    let C = int(Value3);
    let D = int(Value4);
      
    // Set the size of text
    textSize(16);
      
    // Set the text color
    fill(color('red'));
    
    // Getting integer representation
    text("Integer representation of value 'true' is: " + A, 50, 30);
    text("Integer representation of value 'false' is: " + B, 50, 60);
    text("Integer representation of value 'Geeks' is: " + C, 50, 90);
    text("Integer representation of array of values are: " + D, 50, 110);

Output: 
 

Note: From the above program, if the value of the parameter is number then it returns the output as integer representation, for false it returns 0 and for true it returns 1 and for string values, it returns NaN i.e, not a number.
