A non-OO implementation could be an easier start indeed. An issue we may need to discuss about sparse matrices is that NNZ may be larger than integer(4). Also we will...

Thank you @enricofacca for the proposition. A while ago, when I was testing Coarrays, I did something similar to your proposition (see [here](https://github.com/jvdp1/pcgcoarray/blob/36408df93ae5d6515d3bf7d27008aca16780e77e/src/lib/modcoarraysolver.f90#L601)) The idea was that the coefficient matrix...

@St-Maxwell: is this related to the stdlib [`to_string`](https://stdlib.fortran-lang.org/page/specs/stdlib_strings.html#to_string) that support various types? It seems that your implementation does not rely on internal IO (as in stdlib). Therefore, it would be...

Thanks. > A possible extension would be to allow complex arguments, the return value would then be an array with 3 elements for the 3 cube roots (if the number...

> The c++ `cbrt` has the property of `cbrt(-x) == -cbrt(x)` for positive `x`, which makes it not compatible with complex functions. It is equivalent to the [Surd](https://reference.wolfram.com/language/ref/Surd.html) function in...

I am not sure to understand the details. Is the intrinsic `transfer` not what you are looking for? Or maybe [this bitset module](https://stdlib.fortran-lang.org/page/specs/stdlib_bitsets.html)?

I believe so, yes. Thank you.

What is the status of this PR? How can we help to move forward?

Strange... I also tested [this commit bb30a55a53b3728232727a3afdce168900b0be66](https://github.com/fortran-lang/stdlib/pull/552/commits/bb30a55a53b3728232727a3afdce168900b0be66) using Fedora with GCC 11.2.0, and all tests passed. I'll try to look further in the next days...
