A software calculator is a calculator that has been implemented as a computer program, rather than as a physical hardware device.
They are among the simpler interactive software tools, and, as such, they:
- Provide operations for the user to select one at a time.
- Can be used to perform any process that consists of a sequence of steps each of which applies one of these operations.
- Have no purpose other than these processes, because the operations are the sole, or at least the primary, features of the calculator, rather than being secondary features that support other functionality that is not normally known simply as calculation.
As a calculator, rather than a computer, they usually:
- Have a small set of relatively simple operations.
- Perform short processes that are not compute intensive.
- Do not accept large amounts of input data or produce many results.

Famous quotes containing the word calculator:
“Man is a stream whose source is hidden. Our being is descending into us from we know not whence. The most exact calculator has no prescience that somewhat incalculable may not balk the very next moment. I am constrained every moment to acknowledge a higher origin for events than the will I call mine.”
—Ralph Waldo Emerson (18031882)
