A **real** is a number variable that can store whole and decimal numbers. (examples are the *float* and *double* types)

The downside to using **reals** is that **real** variables use more space than integer variables do. **Real** variables should be used for values that need to be as precise as possible.

Examples include points (on a graph or map), distance, and other such values that must be measured in precision.
