The
s
and
R
keys can also be used with variables. For example,
s
(in the MU%C menu) stores the rightmost number from the
display into the variable
M%C
.
R
copies the contents of
M%C
into the calculator line. If there is an expression in the display
(such as
), then the recalled number replaces only the last
number.
You do not need to clear storage registers before using them. By storing
a number into a register, you overwrite whatever existed there before.
