# Numbers & Text > Trig / Exponents

## Conversion

Converts the given number to degrees or radians.

``````Utils.DEG * [NUMBER]

## Constants

### Pi

Returns the value of Pi (3.14159...).

``Math.PI``

### e

Returns e, the base of natural logarithms. (2.718...)

``2.71828``

## Trig Functions

### Sin / Cos / Tan

Returns the result of applying a trigonometric function to the given number. Dropdown for degrees/radians specifies what format the incoming number is in. Supports sin/cos/tan/asin/acos/atan.

``````//Incoming number is Degrees

Math.sin([NUMBER])

//Other operations
Math.cos([NUMBER])
Math.tan([NUMBER])
Math.asin([NUMBER])
Math.acos([NUMBER])
Math.atan([NUMBER])``````

### Inverse Tangent

Converts from rectangular to polar coordinates. The return value is in radians.

``Math.atan2([NUMBER], [NUMBER])``

#### Example: Point Actor Towards Mouse

Using inverse tangent, we can calculate the angle to rotate the actor to based on the mouse's position.

## Exponents

### Square Root

Returns the square root of the given number.

``Math.sqrt([NUMBER])``

### Power

Returns the given number to the specified power (e.g., xy).

``Math.pow([NUMBER], [NUMBER])``

### Natural Logarithm / e Raised to a Power

ln - Returns the natural logarithm of the given number.
e^ - Returns the number e to the given power.

``````Math.log([NUMBER])
Math.exp([NUMBER])``````
