Long doubles make histogram2d fail subtly, maybe add type check?

I'm experimenting with various optimizations in the pulsar search code in HENDRICS (https://github.com/StingraySoftware/HENDRICS/pull/65). One of my bottlenecks was a 2d histogram operation, and I gave a shot to yours. Tested...

Bug: Histogram2d result does not match that of the numpy function

7

Thank you for this package, it is indeed very fast and I am looking forward to using it. There is a discrepancy between your histogram2d function and the numpy equivalent,...

Improve how we generate test cases with hypothesis

1

At the moment, the ``test_1d_compare_with_numpy`` and ``test_2d_compare_with_numpy`` tests are slightly hacky in how they generate test cases. Here's the code for the 1-d case: https://github.com/astrofrog/fast-histogram/blob/4dbb898d1ad221587262cfb609ef5ae93bda7715/fast_histogram/tests/test_histogram.py#L17-L39 What I'm trying to do...

Hey. I was just playing around with this and was trying to see if there's a way to implement this efficiently with standard libs. My usual way to do things...

choice of returned histogram datatype

Thanks for writing this fast histogram package. A task that we astronomers tend to do often and repeatedly :) Coming back to the package itself, it seems to me that...

Add OpenMP

2

I think it should be possible to rewrite the loops to include OpenMP pragmas. The final update could be protected with `#pragma omp atomic` and you can use `default(shared) private(tx...

allow density/normed argument

2

Thank you for your cool package! `numpy.histogram` and `numpy.histogram2d` support the `normed` argument, which divides counts by the number of samples and the bin width/area. It would be great if...
