DEC64: Decimal Floating Point
As a "specification" this document is laughable.  For example, rounding modes and overflow behavior are not addressed.  The comment that object pointers can be stuffed into the coefficient field (usually called 'mantissa') is completely non-sequitur.  Frankly I am surprised to see such a big name behind it.<p>I imagine this project is inspired by the sad state of numerical computing in Javascript, but this proposal will surely only make it worse.  The world certainly doesn't need a new, incompatible, poorly-thought-out floating point format.<p>Compare the level of thought and detail in this "specification" to the level of thought and detail in this famous summary overview of floating point issues: <a href="https://ece.uwaterloo.ca/~dwharder/NumericalAnalysis/02Numerics/Double/paper.pdf" rel="nofollow">https://ece.uwaterloo.ca/~dwharder/NumericalAnalysis/02Numer...</a> ("What every computer scientist should know...")<p>> DEC64 is intended to be the only number type in the next generation of application programming languages.<p>Jesus, I certainly hope not.
