Summary

Function: float llLog10( float val );

Returns a float that is the base 10 "Wikipedia logo"logarithm of val.
If val <= 0 return zero instead.

• float val

To get the "Wikipedia logo"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.
