After a constant is defined and selected, return to the screen

pastes it to the cursor location. In Single mode, only one
defined constant is available for use in calculations, and an
expression using a constant is automatically solved after
pressing @ (without pressing b).

Recalling a Constant in a Series of Calculations
When pressing @ more than once in a series of
calculations, the calculator automatically keeps count for you

includes a list. The counter starts over any time a new entry
precedes @, including Ans.

Count=1.
You recognize that C1=+ 1/2.
The most recently entered
constant (C3) remains
selected.
