Subject: RE: [Caml-list] Float precision in OCaml

Message-ID: <0F7D3B1B3C4B894D824F5B822E3E5A175B2829A1@IRSMSX102.ger.corp.intel.com> (raw)

P.S.:
the discussion on the Maxima list was about what sin(2^1000) should be. At 2^1000 a double LSB is zillions of Pi, so that one can argue that the proper answer should be "something between -1 and 1". The IEEE standard though requires that 2^1000 is treated as an exact number and not as 2^1000 +- 2^(1000-53) and that sin(2^1000) is computed to full precision. The same ideas hold at the small end of numbers.
Best regards,
Michael
