LOG

Purpose:

Calculates the natural logarithm of the specified expression.

Syntax:

LOG(val)

val

A scalar, series or table.

Returns:

A scalar, series, or table.

Example:

log(W1)

creates a new series from the contents of Window 1 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 1.

Example:

log(1)

returns 0, the natural log of 1.

Example:

log(e)

returns 1.

Remarks:

LOG and LN are identical.

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

See LOG1P to compute log(1 + x) for small x.

See LOG10 for log base 10.

See LOG2 for log base 2.
