Exp - gives the exponent of a number system unit

function Exp ( Number : Extended ) : Extended; Description The Exp function takes an integer or floating point Number and raises e (2.72) to that power. This is only used for mathematical processing. Exp has the opposite effect to Ln - the natural logarithm. Related commands Ln Gives the natural logarithm of a number Log10 Gives the log to base 10 of a number Example code : Calculate the exponent of 2 var float : Double; begin // Get the natural logarithm of 2 float := Ln(2); // Show this value ShowMessage('Ln(2) = '+FloatToStr(float)); // Get the exponent of this value - reverses the Ln operation float := Exp(float); // Show this value ShowMessage('Exp(Ln(2)) = '+FloatToStr(float)); end; Show full unit code Ln(2) = 0.693147180559945 Exp(Ln(2)) = 2
