Thanks for opening PR! Need to change the implementation to not continuously cast back to double by using single-precision functions.

[Planeshifter]

The build task dependencies are wrong. The C code (src/main.c) uses single-precision functions (is_nanf, is_infinitef, powf, log10f, lnf, absf, floorf, truncf, float32/base/exponent), but the build dependencies list the double-precision equivalents. This will fail to resolve the correct headers at build time.

The build dependencies should match the benchmark/examples dependencies:

[Planeshifter]

@stdlib/math/base/special/log10f does not exist in the codebase. This include will cause a compilation error.

You'll either need to create log10f as a separate package first, or use stdlib_base_lnf(x) / stdlib_base_lnf(10.0f) for the base-10 case.

[Planeshifter]

We should use the single-precision variants of these, i.e. #include "stdlib/math/base/special/absf.h etc.
