Summary
Function: float llLog( float val );| 265 | Function ID |
| 0.0 | Delay |
| 10.0 | Energy |
Returns a float that is the natural logarithm of val.
If val <= 0 return 0.0 instead.
| • float | val |
To get the base 10 logarithm use llLog10.
Examples
default { state_entry() { float num1 = llFrand(100.0); llOwnerSay("The natural logarithm of " + (string)num1 + " is " + (string)llLog(num1)); } }
Notes
There are only two log functions llLog and llLog10. Errors introduced as a result of floating-point arithmetic are most noticable when working with logarithms. llLog should be used instead of llLog10 when converting the base of the logarithm.
float LogBaseN = llLog(value) / llLog(Base); //This technique introduces errors but is the only way
