Stéphane,
Let me give the following rationale. When parsing with msscanf we get
--> msscanf("1.60009","%lf")==1.6
ans =
T
but
--> msscanf("1.70018","%lf")==1.7
ans =
F
The actual display algorithm does not use msscanf but a
cross-platform code (msscanf

Dear all,
I think that saying that

and that representing it as

With the available decimal places you would represent it as
1.7123456
Wouldn't

1.7 cannot be stored exactly in IEEE754
Yes, but there is an "infinite" amount of decimal numbers
that cannot be stored exactly in IEEE754.
I know... so what ?
