Summary

Function: float llLog10( float val );

264	Function ID
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=llCeil(llLog10(n+1)/llLog10(BASE)) //results in rounding errors.
