relvard 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.
