Take the logarithm of the $x$% WIDTH=17 HEIGHT=16 input port, to base $b$% WIDTH=13 HEIGHT=24 . The base needs to be specified — if the natural logarithm is desired ( $b=e$% WIDTH=72 HEIGHT=24 ), use the natural log instead.

The operator can be placed on the canvas in two ways:

From the Binary Operations (``binop'') toolbar; or
By typing the word ``log'' anywhere on the wiring canvas, and then pressing the Enter key.

When you use the direct typing method to enter the Log operator, the text entry window pops up. This allows you to type a variable/parameter name starting with Log (like, for example, ``Logical''. If you press Enter (or click on OK) with only the word Log in the window, the Log operator will be placed on the canvas.
