[BUG]: The results of pyclipper calculations are inconsistent on x86 and arm architectures

[GenerallyCovetous]

As the title suggests, the single-case test is reproduced below:
import numpy as np
import pyclipper
poly = np.array([[632, 970],
[631, 971],
[630, 971],
[630, 973],
[631, 974],
[631, 975],
[632, 975],
[633, 974],
[633, 973],
[634, 972],
[634, 971],
[633, 971]])
distance = 0.9118854184679032
pco = pyclipper.PyclipperOffset()
pco.AddPath(poly, pyclipper.JT_ROUND, pyclipper.ET_CLOSEDPOLYGON)
result = np.array(pco.Execute(distance), dtype=object)
print(result)

numpy == 1.25.2
pyclipper == 1.2.1
the results on arm machine is [[[634 970]
[635 970]
[635 971]
[634 972]
[634 973]
[633 974]
[632 976]
[631 976]
[630 975]
[630 974]
[629 973]
[629 971]
[630 970]
[631 970]
[632 969]]],
while on x86_64 machine is
[[[634 970]
[635 970]
[635 973]
[634 974]
[634 975]
[633 976]
[632 976]
[630 975]
[630 974]
[629 973]
[629 971]
[630 970]
[631 970]
[632 969]]]
