[RESOLVED] Number Precision: How to explain?

[anhn]

...unfortunately you have been as stubborn as ever.

Yes, I am very stubborn indeed. That might be my problem (or your?) because I cannot make you guys fully understand what I concern.

What I only concern here is with

Single        v = 0.705547500000000       Len(v)= 9 
Double        d = 0.705547511577606       Len(d)= 8 
v=d : True
Double        w = 0.705547500000000       Len(w)= 9 
w=v : True

We have w=d (because w=v and v=d), but d has 15 decimal digits while w has only 7.
Both of them are Double, their displays used the same format string "0.000000000000000".
That's it.

We can stop discuss this topic here. That's enough. No gain, no loss.
