Natural log (base e) of a number (Float class)
The Log and LogE intrinsic functions return a number that is the natural logarithm (the logarithm base ℯ) of the method object value.
LogE is a synonym for Log.
Syntax
%number = float:Log
%number = float:LogE
Syntax terms
| %number | A numeric variable to receive the log of the method object. | 
|---|---|
| float | A Float value. | 
Usage notes
- If float is less than or equal to zero, then the request is cancelled.
 - Log or LogE is an object-oriented version of the $Log function.
 - Log and LogE are available as of Sirius Mods Version 7.3.
 
Examples
The following statement returns 3.14159:log = 1.14472904118518.
printText {~} = {3.14159:log}
