Logarithm

Overview

The Logarithm Node.

Logarithm calculates the logarithm of a number in a chosen base.

This is the inverse function of the Power Node. Rather than taking a base value, raising it to the power of an exponent, and returning the power, it takes the base value, along with the power, and returns the exponent.

Scope: Project, Scene, Function, Prefab.

Attributes

The Logarithm Node Attributes.

Inputs

Attribute	Type	Description
Base	Drop-down	A selection of common bases used in logarithm functions, which are: 2 (binary), e (natural), or 10 (common), as well as a Custom option, for defining a custom base value.

Default

Attribute	Type	Description
Base Value (Made available by the Base Attribute set to Custom)	Float	A custom base value.

Inputs

Input	Type	Description
Pulse Input (►)	Pulse	A standard input Pulse, to trigger the execution of the Node.
Input	Float	The number whose logarithm you wish to calculate.

Outputs

Output	Type	Description
Pulse Output (►)	Pulse	A standard output Pulse, to move onto the next Node along the Logic Branch, once this Node has finished its execution.
Exponent	Float	The logarithm of Input in the chosen base.
