Standard Operations

Arithmetic Power of

The "**" operator is defined as arithmetic power of for all numeric types.

function "**" (Left : T; Right : Integer) return T;

Usage

A : constant Float   := 5.0 ** 2;  -- A is now 25.0
B : constant Integer := 5 ** 2;    -- B is also 25

Working Example

File: operator_power.adb (view, plain text, download page, browse all)

with Ada.Text_IO;

procedure Operator_Power is
   A : constant Float   := 5.0 ** 2;  -- A is now 25.0
   B : constant Integer := 5 ** 2;    -- B is also 25

   package T_IO renames Ada.Text_IO;
   package F_IO is new  Ada.Text_IO.Float_IO (Float);
   package I_IO is new  Ada.Text_IO.Integer_IO (Integer);

begin
   T_IO.Put ("A = ");
   F_IO.Put (
      Item => A,
      Fore => 3,
      Aft  => 1,
      Exp  => 0);
   T_IO.New_Line;
   T_IO.Put ("B = ");
   I_IO.Put (
      Item  => B,
      Width => 3,
      Base  => 10);
   T_IO.New_Line;
end Operator_Power;
