How to make Ada math function use double precision (Long float)variables?

Ada's standard math functions such as sin, cos, *, /, etc support Float type variables only as input and output. Is it possible to make these functions deal with double precision or long_float for both input and output variables?

Solution

  • Actually math functions are (fortunately) supported for any precision.

    with Ada.Numerics.Generic_Elementary_Functions;

...

  type Real is digits 15;

  package REF is new Ada.Numerics.Generic_Elementary_Functions (Real);

  use REF;
