Terminating Digit Entry. When keying in two numbers to
perform an operation, the calculator needs a signal that digit entry
has been terminated for the first number. This is done by pressing
to separate the two numbers. If, however, one of the
numbers is already in the calculator as the result of a previous
operation, you do not need to use the
key. All functions
except the
digit entry
keys
themselves
have the effect of
terminating digit entry.*

is used to separate two numbers sequentially
keyed into the stack.
