ln
Description
Computes the natural logarithm (base e) of a number.
Syntax
Like many functions in DataPrime, ln supports two notations, function and method notation. These interchangeable forms allow flexibility in how you structure expressions.
Arguments
| Name | Type | Required | Description | 
|---|---|---|---|
| number | number | true | The number whose natural logarithm will be computed | 
Example
Use case: Model exponential growth with Euler's number and natural logarithm
Calculate the growth rate from observed data, then project future values using e and ln.
