should be 3.141592653589793
nothing demands to round OFF pi 3.141592653589790

Reconciliation . . .

1. Mathcad 11 XP default π 3.141592653589790

last decimal valued . . . . . 3.141592653589793

2. Mathcad 11 XP same freak mantissa as Smath

3. Mathcad 11 XP symbolic mantissa OK.

4. Freaks suspected from Windows

5. Undemanded round OFF ► Windows bug

6. maple does not verdict !
