Hello A.Z.
As Raffaello said, Java arithmetic does not have any more problem than
C/C++ when using IEEE 754. The "proof" of contrary is only an illusion
due to the rounding behavior of C/C++ output routines, as demonstrated
by Raffaello's code. Maybe some C/C++ code use Intel extended precision
arithmetic (80 bits instead of 64 bits), but it only pushes the problem
further, it still not an exact representation of decimal numbers. Exact
representation of 0.1 using base 2 is mathematically impossible, no
matter the language (it is a periodic number in base 2).
Regards,
Martin
