Relating to or based on the number ten; using or relating to a base-ten number system.
From Latin 'decad-' (ten) + '-ic' (suffix meaning 'relating to' or 'characterized by'). This adjective describes anything based on or pertaining to the number ten, especially the decimal or base-ten numerical system.
