# Math

The `Math` Class provides a comprehensive set of mathematical functions and constants for a wide range of mathematical operations. It includes well-known mathematical constants such as 'e' (the base of natural logarithms) and 'pi' (the ratio of a circle's circumference to its diameter). The Math Class also offers methods for tasks like rounding numbers, generating random values, and converting angles between degrees and radians.

### Constants

**`Math.E`**

The constant representing the mathematical constant 'e,' the base of natural logarithms.

**`Math.PI`**

The constant representing the mathematical constant 'pi,' the ratio of the circumference of a circle to its diameter.

**`Math.DEGREES_TO_RADIANS`**

A constant for converting angles from degrees to radians.

**`Math.RADIANS_TO_DEGREES`**

A constant for converting angles from radians to degrees.

### Methods

**`Math.round(a: number): number`**

Returns the closest `long` to the argument `a`, with ties rounding to positive infinity.

```typescript
var number = 3.7;
var roundedNumber = Math.round(number); // roundedNumber is now 4
```

**`Math.random(): Double`**

Returns a random `double` value with a positive sign, greater than or equal to 0.0 and less than 1.0.

```typescript
var randomNumber = Math.random();
// Generates a random number between 0.0 (inclusive) and 1.0 (exclusive)
```

**`Math.nextUp(num: number): number`**

Returns the floating-point value adjacent to the argument `num` in the direction of positive infinity.

```typescript
Math.nextUp(1); // returns 1.0000001 
```

**`Math.nextDown(num: number): number`**

Returns the floating-point value adjacent to the argument `num` in the direction of negative infinity.

```typescript
Math.nextDown(1); // returns 0.9999999
```

**`Math.sqrt(num: number): double`**

Returns the square root of a number in a double.

```typescript
var number = 16;
var squareRoot = Math.sqrt(number); // squareRoot is now 4.0
```
