Log (e) Node

The Log (e) node calculates the natural logarithm (base e) of a number.

Log (e) Node

Description​

The Log (e) node calculates the natural logarithm (logarithm with base e ≈ 2.718) of a numeric value. For non-positive inputs, the result will be NaN (not a number).

Execution Inputs​

None (data node, no execution flow)

Variable Inputs​

  • Value (number): The number to calculate the natural logarithm of

Execution Outputs​

None (data node, no execution flow)

Variable Outputs​

  • Result (number): The natural logarithm of the input value

Special Notes​

  • If the input cannot be parsed as a number, the result defaults to "0.0"
  • Non-positive inputs (zero or negative) will produce NaN (not a number)
  • This node doesn't have execution pins - it's a pure data node

Example Usage​

Calculate natural logarithms for mathematical operations, exponential growth calculations, or scientific computations. Connect a number output to the Value input, then use the Result output in other calculations or comparisons.
