function Ln(const X: Extended): Extended;
The Ln function takes an integer or floating point Number and gives the natural logarithm of that number. This is only used for mathematical processing.
Ln has the opposite effect to Exp - the exponent of a number.
Example
var
float,number : float;
{
number = 2.14;
float = Ln(number);
ShowMessage('Ln('+FloatToStr(number)+') = '+FloatToStr(float));
float = Exp(float);
ShowMessage('Exp(Ln('+FloatToStr(float)+')) = '+FloatToStr(float));
}
Output:
Ln(2,14) = 0,76080582903376
Exp(Ln(2,14)) = 2,14
