| |
| <p>Operators must be defined on values of specific types. For instance, |
| <code>+</code> is defined on numbers, but not on characters or other non- |
| arithmetic types. Operators are often defined on groups of types. |
| </p> |
| <dl compact="compact"> |
| <dt><code>**</code></dt> |
| <dd><p>The exponentiation operator. It raises the first operand to the power |
| of the second one. |
| </p> |
| </dd> |
| <dt><code>:</code></dt> |
| <dd><p>The range operator. Normally used in the form of array(low:high) to |
| represent a section of array. |
| </p> |
| </dd> |
| <dt><code>%</code></dt> |
| <dd><p>The access component operator. Normally used to access elements in derived |
| types. Also suitable for unions. As unions aren’t part of regular Fortran, |
| this can only happen when accessing a register that uses a gdbarch-defined |
| union type. |
