## Example

A fixed point type definition specifies a *delta*, and a range. Together, they describe how precisely real values should be approximated as they are represented by powers of two, not using floating point hardware.

```
Shoe_Ounce : constant := 2.54 / 64.0;
type Thickness is delta Shoe_Ounce range 0.00 .. 1.00;
Strop : Thickness := 0.1; -- could actually be 0.09375
```
