To get the natural logarithm use llLog.

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

Returns a float that is the base 10 logarithm of val.

If val <= 0 return zero instead.

How to use
float result = llLog10(0.0);

Examples

Section titled “Examples”
Example 1
default
{
  state_entry()
  {
    float num1 = llFrand(100.0);


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

Notes

Section titled “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
