Description:
A full function calculator that includes a virtual paper tape that records all entries and operations made on the calculator.
Instead of re-doing an entire operation to check one's work, the user need only review the contents of the papertape.
The papertape also simplifies some complex calculations such as linear regression since more than one value can be displayed on the papertape at a time and in a variety of formats.
Overlong lines are shown on the next line; scrolling is simplified. Display of scientific notation is also improved on both the display and the papertape.
Memory locations store text with the numbers to allow for labels and units to describe the number.
