### 8.1 Intrinsic Operators

All the predefined numeric operators in package Standard
in pragma Import (Intrinsic,..)
declarations. In the binary operator case, the operands must have the same
size. The operand or operands must also be appropriate for
the operator. For example, for addition, the operands must
both be floating-point or both be fixed-point, and the
right operand for "**" must have a root type of
Standard.Integer'Base.
You can use an intrinsic operator declaration as in the following example:

type Int1 is new Integer;
type Int2 is new Integer;
function "+" (X1 : Int1; X2 : Int2) return Int1;
function "+" (X1 : Int1; X2 : Int2) return Int2;
pragma Import (Intrinsic, "+");

This declaration would permit 'mixed mode' arithmetic on items
of the differing types Int1 and Int2.
It is also possible to specify such operators for private types, if the
full views are appropriate arithmetic types.
