    64 bit vs 32 bit data feeds

    Could someone enlighten me as to why data feeds need to be 64 bits?

    My real question is "how beneficial is a 64 bit trading platform?"

    BTW - I've done extensive programming where 64 bit doubles where essential because we were holding calculations that were precise out to about 15 digits.... (we also found that 64 bit was too imprecise for most of our calcs, and converted to long long and back to double)

    But price is only 2 or 3 digits precise, so why the trouble of 64 trading platforms?

    I'm always conscious of using the smallest data type I need, and am trying to understand why I would need to use a 64 bit datatype for trading.

    Could someone enlighten me as to the benefits and help me change my understanding of this?

    Thanks

    Matt

    There is a misunderstanding: .NET code for 32bit and 64bit is exact the same, data types are EXACT the same etc. Please consult MS docs for how the .NET runtime works.

    There are some principle benefits on 64bit apps vs. 32bit app like available address space. Please consult the MS docs for details.
