LN

Purpose:

Calculates the natural logarithm of the specified expression.

Syntax:

LN(val)

val

A scalar, series or table.

Returns:

A scalar, series, or table.

Example:

ln(W2)

creates a new series from the contents of Window 2 and places the result in the current Window. The value of each point in the new series will be the natural logarithm (base e) of the corresponding point in Window 2.

Example:

ln(1)

returns 0, the natural log of 1.

Example:

ln(e)

returns 1.

Remarks:

LN and LOG are identical.

For x < 0, ln(x) returns a complex result.

See LOG10 for log base 10.
