Note:
Executed expressions are stored in a
temporary memory in the executed order. If the temporary
memory is full, the oldest data is automatically deleted. Be aware
that
e
may not function on these occasions.
A maximum of 160 bytes can be stored in the temporary memory.
The capacity may vary when there are division codes between
expressions.
When switching from
equation edit mode
to
one-line edit mode
in the SETUP menu, all the numerical and graph equations stored
in the temporary memory are cleared and cannot be recalled.
