Middle English, from Old French, from Latin compl&emacron;mentum, from compl&emacron;re, to fill out; see complete. Usage Note: Complement and compliment, though quite distinct in meaning, are sometimes confused because they are pronounced the same. As a noun, complement means “something that completes or brings to perfection” (The antique silver was a complement to the beautifully set table); used as a verb it means “to serve as a complement to.” The noun compliment means “an expression or act of courtesy or praise” (They gave us a compliment on our beautifully set table), while the verb means “to pay a compliment to.”complement

complement - Computer Definition
The number derived by subtracting a number from a base number. For example, the tens complement of 8 is 2. In set theory, complement refers to all the objects in one set that are not in another set. Complements are used in digital circuits, because it is faster to subtract by adding complements than by performing true subtraction. The binary complement of a number is created by reversing all bits and adding 1. The carry from the high-order position is eliminated. The following example subtracts 5 from 8. Decimal Binary Complement 8 1000 1000 -5 -0101 +1011 __ _____ _____ 3 0011 0011
