Relating to or used for calculation; suitable for performing mathematical computations.
From Latin calcularius, from calculare. This term was more common in early modern English and has largely fallen out of use, replaced by more modern terms like 'computational.'
Calculary is a wonderful example of 'obsolete vocabulary'—it was a perfectly good technical term that gradually disappeared as English developed newer, more intuitive alternatives like 'computational' and 'mathematical.'
