Unity's

Mathf

class provides a collection of common math functions, including trigonometric, logarithmic, and other functions commonly required in Unity projects. It's a Unity-specific alternative to the .NET

System.MathF

class.

The following sections cover some of the key features of the class. For a full reference of every member of the class, refer to the

Mathf

API reference.

All Unity's trigonometry functions work in radians:

PI

is available as a constant, and you can multiply by the static values

Rad2Deg

or

Deg2Rad

to convert between radians and degrees.

The class includes the following common power and square root functions:

It also provides power-of-two related functions. These are useful when working with common binary data sizes, which are often constrained or optimized to power-of-two values (such as texture dimensions):

The interpolation functions allow you to calculate a value somewhere between two given points. Each of these functions behaves in a different way, suitable for different situations. For more information, refer to the examples in each method's API reference:

Vector classes and the

Quaternion

class all have their own interpolation functions (such as

Quaternion.Lerp

) for interpolating positions, directions, and rotations in multiple dimensions.

The following helper functions are often useful in games or apps and can save time when you need to limit values to a certain range or repeat them within a certain range:

The

Log

function allows you to calculate the logarithm of a specified number, either the natural logarithm or in a specified base. Additionally the

Log10

function returns the base-10 logarithm of the specified number.
