## Context: the new `global_dtype` fixture and `SKLEARN_RUN_FLOAT32_TESTS` environment variable

Introduction of low-level computational routines for 32bit motivated an extension of tests to run them on 32bit.

In this regards, https://github.com/scikit-learn/scikit-learn/pull/22690 introduced a new `global_dtype` fixture as well has the `SKLEARN_RUN_FLOAT32_TESTS` env. variable to make it possible to run the test on 32bit data.

Running test on 32bit can be done using `SKLEARN_RUN_FLOAT32_TESTS=1`.

For instance, this run the first `global_dtype`-parametrised test:
