The quality or state of being computative; the degree to which something can be computed or expressed mathematically.
From 'computative' + '-ness' suffix, ultimately tracing to Latin 'computare' (to calculate). The '-ness' suffix creates an abstract noun expressing a quality or condition.
This word is so technical and rare that it appears almost exclusively in academic philosophy and computer science papers discussing whether phenomena possess 'computativeness'—the philosophical property of being reducible to computation.
