When you recall
a
number, it is copied from
the
storage register
into the display, and
it
also remains
in
the storage register. You
can recall a
number
from a storage register any
number
of times
without altering it-the number
will
remain
in the storage
register as a 10-digit
number
with a two-digit exponent of 10
until
you overwrite it by storing another
number
there, or until
you clear the storage registers.
Example:
Three tanks have capacities
in
U.S.

of 2.0,
14.4,
and 55.0 gallons, respectively. If one U .S
.
gallon is
approximately equal to 3.785
liters,
what is the capacity of each
of
the tanks
?
Method:
Place the conversion constant
in
one of the storage
registers and bring it out as
required
