Hm ok, then I will port the offical Ryu test cases to Pascal (from https://github.com/ulfjack/ryu/blob/master/ryu/tests/ ). for to see further.

BeRo1985 avatar BeRo1985 commented on May 25, 2024

So, I've ported the relevant parts of the offical Ryu test cases to Pascal, which passes also as whole without one error.

So what is left are probably then Ryu-Algorihm concept conditional differences to ensure e.g. roundtrips and other special characteristics. And since the Ryu paper ( https://dl.acm.org/citation.cfm?doid=3296979.3192369 ) has been peer reviewed several times, and since the one paper has also complete correctness proof of the algorithm, I would classify the Ryu algo as correct here. Even my reimplementation so far, since it passes also all offical Ryu testcase tests.

The only difference to the original C implementation of the Ryu algorithm so far is that my reimplementation has no limit to a maximum count of to parsing 17 digits by dynamically truncating and roundig all further digits when needed.

But please recheck it again anyway :-)

So, after reading https://www.exploringbinary.com/decimal-to-floating-point-needs-arbitrary-precision/ i've reworked the slow path double parsing by parsing to a temporary 512-bit floaing point value, which breaking-tie-even-rounded down to a 64-bit floating point afterwards. But this new slow path is damn slow. So i'll implement more fine-tuned algo variants in between in the next days, from very fast (Eisel-Lemire), then fast (ryu) and then to damn slow (float512).

Anyway, please recheck it. :-)

That would be perfect

Perhaps this is faster than damn slow: https://nigeltao.github.io/blog/2020/parse-number-f64-simple.html ?

BeRo1985 avatar BeRo1985 commented on May 25, 2024

I have now implemented an additional a bit faster but still slow big-integer-based "Algorithm M" fallback path, but it currently only works for base 10. For the other bases (2 binary, 4, 8 octal, 16 hex) I will extend the algorithm in the next days, and when I am done with it, I will remove the old float512 fallback path.

The 64-bit version passes all these tests

But with the 32-bit version there seems to be a problem in ComputeFloat64.

    ComputeFloat64( -22 , 3053, ...) = 3.0530000000000002E-019     //32-bit

    ComputeFloat64( -22 , 3053, ...) = 3.0529999999999998E-019     //64-bit

from pasdblstrutils.

BeRo1985 avatar BeRo1985 commented on May 25, 2024

Ok it seems, I've found out the issue. It is, or better, it was the FPU-using fast path of ComputeFloat64. Maybe I should IFdef'ing it out as whole, except for x86-64 and AArch64.

from pasdblstrutils.

benibela avatar benibela commented on May 25, 2024

So 32-bit used FPU and 64-bit used SSE. Then the 32-bit fast path works after SetPrecisionMode(pmDouble);

from pasdblstrutils.

BeRo1985 avatar BeRo1985 commented on May 25, 2024

The big-integer-based "Algorithm M" fallback path can also process base 2, base 4, base 8 and base 16 inputs.
