minus-squaremarcos@lemmy.worldlinkfedilinkarrow-up1·2 个月前Do you have a computer type that can represent the entire rational set?
minus-squarecalcopiritus@lemmy.worldlinkfedilinkarrow-up4·2 个月前Yes. Have a structure with 2 BigInts. Treat one as the numerator. The other as denominators. It might not be efficient or fast. But it is possible.
minus-squaremarcos@lemmy.worldlinkfedilinkarrow-up1·2 个月前You are proposing that can represent the entire rational set?
minus-squarecalcopiritus@lemmy.worldlinkfedilinkarrow-up2arrow-down1·edit-22 个月前Yes that is correct. A BigInt represents the entire integer set. Rational numbers are defined by just 2 integers. Therefore, 2 BigInts represent the entire rational set.
minus-squareWhiskyTangoFoxtrot@lemmy.worldlinkfedilinkarrow-up3·2 个月前No. They all need to mimic certain numbers.
minus-squaremarcos@lemmy.worldlinkfedilinkarrow-up1·2 个月前So, you have a notation that can represent the entire rational set? What exactly is being mimicked?
minus-squareWhiskyTangoFoxtrot@lemmy.worldlinkfedilinkarrow-up1·2 个月前 So, you have a notation that can represent the entire rational set? No. That’s not what the meme is about, and that’s not what we’re arguing about. What exactly is being mimicked? Fractions.
Show how 1/3 can be precisely represented in floating point.
fl_numerator = 1
fl_denominator = 3
And division is a “stretch goal” once we get funding.
How many decimal places can it be stretched?
