fractionalstd2inner 1.0.5

the cython-based fractions system used for td2inner(an internal part of timediffz)

fractionalstd2inner

A high-performance Cython + GMP, very basic and custom implementation of Python’s built-in fractions library.
It is ~1.5× to 4× faster than the standard Python implementation and was made to be used internally by
td2inner.

⚠️ This package must be compiled locally.
No prebuilt wheels are provided.

⚠️ Important Notice (Read This First)

fractionalstd2inner contains a native Cython extension that depends on
GMP (GNU Multiple Precision Arithmetic Library).

Because of this:

• ❌ No prebuilt wheels
• ✅ Development tools are required
• ✅ Compilation occurs during pip install

This is intentional.
