ln

The ln function can be used in custom filters and table calculations to get the natural logarithm of a value.

Syntax

ln(value)

The ln function takes the logarithm of a value to the base of the mathematical constant e .

Examples

The ln function can be used to model exponential growth linearly by taking ln of the dependent variable. For example:

 ln(order_items.growth_rate) 

Things to know

ln can be used to give you the time needed to reach a certain level of growth. For instance, modeling growth exponentially as:

growth = e ^time

time can be determined using ln as follows:

 ln(growth)
