The instruction performs natural logarithm calculation on the values in (IN) and places the result in (OUT).

To obtain a base 10 logarithm from natural logarithm, divide the natural logarithm by 2.302585 (approximately equal to the natural logarithm of 10).

To elevate any real number to a power of another real number, including fractional exponentiation: combine the "natural exponent" instruction with the "natural logarithm" instruction. For example, to raise X to a power of Y, enter the following command: EXP (Y * LN (X)).
