Frequently asked questions
How does the calculator decide what counts as the stem versus the leaf? For two-digit numbers it splits each value's tens digit as the stem and its ones digit as the leaf; numbers with more digits are grouped by all leading digits except the last as the stem.
Can this handle decimal numbers? It's designed for whole numbers, since the stem-and-leaf format relies on splitting a value into leading and trailing digits; decimals would need to be rounded or rescaled first to fit the format.
