Logarithm

Overview

Logarithm performs 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.

Exponentiation-Related Nodes

The Power, nth Root, and Logarithm Nodes each relate to exponentiation. They all take two known parameters and return the 3rd unknown Value.

Attributes

Attribute	Type	Description
Base	Drop-down	A selection of common bases used in logarithm functions, which are: 2 (binary), e (natural) or 10 (common).

Inputs

Input	Type	Description
Pulse Input (►)	Pulse	A standard Input Pulse, to trigger the execution of the Node.
Input	Float	The power or antilogarithm to be used, along with the base.

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.
Output	Float	The logarithm of the base and antilogarithm.
