The sqrt() function in p5.js is used to get the square root of any input number.

Syntax:

sqrt(n)

Parameters: This function accepts single parameter n which is an input non-negative number whose square root is being calculated.

Return Value: It returns the square root of any input number.

Below program illustrates the sqrt() function in p5.js:

Example: This example uses sqrt() function to get the square root of an input number.

function setup() {

    // Create Canvas of size 270*80
    createCanvas(350, 80);
}

function draw() {

    // Set the background color
    background(220);

    // Initialize the parameter
    let a = 25;
    let b = 16;

    // Call to sqrt() function
    let x = sqrt(a);
    let y = sqrt(b);

    // Set the size of text
    textSize(16);

    // Set the text color
    fill(color('red'));

    // Getting output
    text("Square root of 25 is: " + x, 50, 30);
    text("Square root of 16 is: " + y, 50, 50);
}

Output:
