Logarithm/Powers

Bessel functions

Miscellaneous

Returns the natural logarithm of a number.

LN(number)

returns the natural logarithm (the logarithm to base e) of number, that is, the power of e necessary to equal number.

The mathematical constant e is approximately 2.71828182845904.

LN(3)

returns the natural logarithm of 3 (approximately 1.0986).

LN(EXP(321))

returns 321.
