What does the ceiling function do to a decimal like 3.7?

The ceiling function rounds 3.7 up to the next whole integer, returning 4, because 4 is the smallest integer greater than or equal to 3.7.

If I enter an integer like 7, what will the calculator output?

The calculator returns the original number 7 unchanged, since 7 is already an integer and the smallest integer greater than or equal to itself.

Where is the ceiling function symbol used outside of mathematics?

In programming languages, the ceiling function is most often called using the command ceil(x), which forms the basis for algorithms in various digital calculators.

Can the calculator graph the ceiling function for me?

The site explains how to graph the ceiling function in its accompanying article, but the calculator itself does not generate an interactive graph; users must refer to the text and examples provided.
