Number Storage and Storage Register Arithmetic
53
With the exception of the statistics registers, you can also use \w and v for
application registers. For example, \wÒ stores the number from the display in the
Ò register. vÒ copies the contents from Ò to the display.
In most cases, it is unnecessary to clear a storage register since storing a number replaces the
previous contents. However, you can clear a single register by storing 0 in it. To clear all the
registers at once, press \N.
