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 / LogE are object-oriented versions of the Rocket function: $Log.
- Log / LogE are available as of "Sirius Mods" Version 7.3.
Examples
- The following statement returns "
3.14159:log = 1.14472904118518".printText {~} = {3.14159:log}

- PrintText is described in the "System Intrinsic Class".
