p5.js | int() function

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.
