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.
llLog10 should only be used where the base 10 log is needed, all other applications should use llLog instead.

Examples

default
{
  state_entry()
  {
    float num1 = llFrand(100.0);

    llOwnerSay("The base 10 logarithm of " + (string)num1 + " is " + (string)llLog10(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
