|
|
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.
|
|
|
|
<dl>
|
|
<dt><code>**</code><dd>The exponentiation operator. It raises the first operand to the power
|
|
of the second one.
|
|
|
|
<br><dt><code>:</code><dd>The range operator. Normally used in the form of array(low:high) to
|
|
represent a section of array.
|
|
|
|
<br><dt><code>%</code><dd>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.
