Numbers should be stored and processed as strings. That way, they are always 100% accurate. 
|
|
|
|
|
BCD is more compact and is exact as well.
|
|
|
|
|
No need to argue - string and BCD representation are equally good at representing values such as e and pi.
|
|
|
|
|
BCD takes half the space. On top of this, all processors derived from the Intel 8080 contain instructions for efficient calculations with BCD.
|
|
|
|
|
They have one serious limitation if the task is to represent e and pi "100% accurate", as Marc Clifton wrote:
The number of address pins is below ∞. With BCD, ∞-1 address pins is enough, but it happens that ∞-1 = ∞.

The real question is how posits behave with a long sequence of operations. The advantage of traditional floating-point numbers is that their behaviour and accuracy are well-understood. This allows using certain Numerical Analysis theorems to analyze algorithmic errors, etc.
Replacing floating-point numbers with posits will require throwing away much of Numerical Analysis as it currently exists, and redeveloping it for this new format. Doing so must have major advantages, or posits will remain nothing more than a curiosity.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

That's only needed to use them for scientific/engineering purposes.
When you just throw a datacenter at at the wall repeatedly until whatever sticks looks like what you wanted, all you have is a black box. Numerical error propagation is infinitely beyond the scope of what you don't understand about it.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

Perhaps I didn't explain myself clearly.
The development of a "Machine Learning" model requires quite a bit of scientific/engineering-style mathematics, in order to calculate the parameters for the model. These typically involve best-fit (linear or otherwise), differentiation in multiple dimensions, etc. Using ill-understood posits for the calculations, rather than better-understood floating point, just adds additional uncertainty to the results.
Many theorems used in Numerical Analysis depend on esoteric issues such as the base of the floating-point numbers, the method used to round them, etc. Until a similar body of work is produced for posits, using them in any large calculation would be a bad idea. This does not mean that it won't be done.

Twitter user and IT engineer Thomas Førde found out their network printers had gone missing after updating to the Windows 11 22H2 feature update. Good thing we're all paperless

Developers are tracking what components are used in software, but most of them don't sign-off on code changes, suggesting a long road ahead for protecting the software supply chain. A happy developer is a secure developer

Microsoft recently advanced .NET MAUI to General Availability status, but many developers have complained about half-baked functionality that was shipped too soon. Microsoft never ships a product until it is ready!
OK, that made me giggle my coffee out my nose. Apologies if anyone hurts themselves on that blurb.
