Summary
Function: float llLog10( float val );| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a float that is the base 10 
logarithm of val.
If val <= 0 return zero instead.
| • float | val |
To get the natural logarithm use llLog.
Caveats
- there is no function for log2(n) or other bases than 10 or e.
integer logBASEn=llLog10(n)/llLog10(BASE) //results in rounding errors.
Examples
default
{
state_entry()
{
float num1 = llFrand(100.0);
llOwnerSay("The base 10 logarithm of " + (string)num1 + " is " + (string)llLog10(num1));
}
}
