| Bounds define a lower bound, upper bound, or inequality for a certain value. |
| They work on numbers, strings, bytes, and and null. |
| |
| The bound is defined for all values for which the corresponding comparison |
| operation is define. |
| For instance `>5.0` allows all floating point values greater than `5.0`, |
| whereas `<0` allows all negative numbers (int or float). |
