[Numpy-discussion] Canonical way of serialising Generators

2024-10-27 Thread Andrew Nelson via NumPy-Discussion
Hi all, is there a canonical way of serialising Generators (not via pickle). Would the following be reasonable for saving and restoring state: ``` def serialize_rng(rng): klass = rng.bit_generator.state['bit_generator'] entropy = rng.bit_generator.seed_seq.entropy return klass, entropy

[Numpy-discussion] Exact representable difference between for two arrays.

2024-12-19 Thread Andrew Nelson via NumPy-Discussion
Hi all, Let's assume we have two float arrays, `x0` and `h`, both of which have the same shape. Let's calculate the sum of those two arrays: ``` x1 = x0 + h ``` The true representable difference between `x1` and `x0` is: ``` dx = x1 - x0 ``` Is it also possible to get that exact representation
