// Assign the radius of the circle to the constant radius
const radius = 10;

// Calculate the area of the circle
const area = Math.PI * Math.pow(radius, 2);

// Output the area of the circle
console.log('The area of the circle is ' + area + '.');


// Math.max: maximum value, Math.min: minimum value
const max = Math.max(3, 7, 2, 8, 5);
const min = Math.min(3, 7, 2, 8, 5);

// Output maximum and minimum values
console.log('Maximum value:', max);
console.log('Minimum value:', min);

# Math Object

JavaScript offers various functionalities to help solve mathematical problems.

The `Math` object provides various methods and constants to help with mathematical operations.

 

## Basic Constants

- `Math.PI`: Returns the value of π (Pi), which is the ratio of a circle's circumference to its diameter.

```javascript title="Output the value of Pi"
console.log(Math.PI); // 3.141592653589793
```

Using Math.PI, you can easily calculate the area or circumference of a circle.

 

## Rounding, Ceiling, Flooring

- `Math.round(number)`: Rounds the number to the nearest integer.

```javascript title="Math.round Rounding"
console.log(Math.round(4.7)); // 5
console.log(Math.round(4.4)); // 4
```

 

- `Math.ceil(number)`: Rounds the number up to the nearest integer.

```javascript title="Math.ceil Ceiling"
console.log(Math.ceil(4.2)); // 5
```

 

- `Math.floor(number)`: Rounds the number down to the nearest integer.

```javascript title="Math.floor Flooring"
console.log(Math.floor(4.7)); // 4
```

 

## Maximum, Minimum Values

- `Math.max(number1, number2, ...)`: Returns the largest of the given numbers.

- `Math.min(number1, number2, ...)`: Returns the smallest of the given numbers.

```javascript title="Output maximum and minimum values"
console.log(Math.max(3, 7, 2, 8, 5)); // 8
console.log(Math.min(3, 7, 2, 8, 5)); // 2
```

 

## Power, Square Root

- `Math.pow(base, exponent)`: Returns the base to the exponent power.

```javascript title="Output power value"
console.log(Math.pow(2, 3)); // 8 (2 raised to the power of 3)
```

 

- `Math.sqrt(number)`: Returns the square root of the given number.

```javascript title="Output square root value"
console.log(Math.sqrt(16)); // 4 (square root of 16)
```

The Math.floor method rounds a value down to the nearest integer less than or equal to the given number. For example, Math.floor(4.7) returns 4.
