(Any reason you didn't instantiate with My_Float?)


For illustration, inserting Put(Var3, Aft => 15) and
Put(Var4, Aft => 15), I get

$ ./test_fpt
var3:  9.999000244140625E+02=
var4:  9.999000854492188E+02>

Choosing 15 digits instead of 6 in the type definition, I get

$ ./test_fpt
var3:  9.999000000000000E+02=
var4:  9.999000000000001E+02>

There is always a FPT computation that isn't giving the exact
result, since there aren't enough bits for doing real math on
any computer, if you try hard enough.
