llLog10

float llLog10(float Value)

Returns the base 10 logarithm of Value. Returns zero if Value <= 0.

Returns the base 10 (common) logarithm of the specified Value.

Parameters

Value (float)

Technical Details

Return Type: float
Energy: 10

  }
}

Notes

There are only two log functions: llLog and llLog10
llLog10 should only be used where the base 10 log is needed; all other applications should use llLog instead

Use llLog when converting the base of the logarithm:

float LogBaseN = llLog(value) / llLog(Base); //This technique introduces errors but is the only way

Errors introduced as a result of floating-point arithmetic are most noticeable when working with logarithms
