Package: gnat-3.1
Version: 1:3.1-2
Severity: normal
With the following code:
---CUT---
with Ada.Text_IO;
use Ada.Text_IO;
with Ada.Numerics;
use Ada.Numerics;
with Ada.Numerics.Generic_Elementary_Functions;
procedure TestBug2 is
type F is new Float;
subtype Radians is F;
package Maths is new Generic_Elementary_Functions(F);
use Maths;
begin
Ada.Text_IO.Put_Line(F'Image(Sin(5.49779)));
Ada.Text_IO.Put_Line(F'Image(Sin(0.0)));
Ada.Text_IO.Put_Line(F'Image(Sin(5.49779)));
end TestBug2;
---CUT---
It returns:
0.E+05
-0.00000E+00
0.00000E+00
I think the first number is NaN (at least according to the patched gdb
5.0 it was), not sure why the last one is different.
According to Gnome Calculator, sin(5.49779)==0.707, and sin(0)==0.
I never had any problems with sin/cos/arcsin using the old version of
gnat (but didn't run this test program).
