# p5.js | pow() function

The pow() function in p5.js is used to calculate the power of a number to the given number. It is an efficient way of multiplying numbers by themselves (or their reciprocals) in large quantities.

Syntax

```pow( n, e )
```

Parameters: The function accepts two parameters as mentioned above and described below:

• n: This parameter stores the base of the exponential expression.
• e: This parameter stores the power by which to raise the base.
• Below program illustrates the pow() function in p5.js:

Example: This example uses pow() function to calculate power of a number.

 `function` `setup() { ` ` `  `    ``// Create Canvas of size 270*80   ` `    ``createCanvas(350, 80); ` `} ` `  `  `function` `draw() { ` `     `  `    ``// Set the background color ` `    ``background(220); ` `     `  `    ``// Initialize the parameter   ` `    ``let n = 3; ` `    ``let e = 4; ` `     `  `    ``// Call to pow() function ` `    ``let y = pow(n, e); ` `     `  `    ``// Set the size of text ` `    ``textSize(16); ` `     `  `    ``// Set the text color ` `    ``fill(color(``'red'``)); ` `     `  `    ``text(``"Given number is "` `+ n + ``" and exponent is "`  `            ``+  e + ``" "``, 50, 30); ` `    ``text(``"Computed Number is : "` `+ y, 50, 50); ` `} `
