Other forms: exacting; exacted; exacts; exactest; exacter; exactingly
If something's exact, it's precise and completely accurate — as opposed to a guess, an estimate, or an approximation.
Exact also has the meaning of taking something from someone, often money, and generally only given up with reluctance under the threat of force. The Mob might exact a shakedown from unfortunate businessmen, for example. The word comes from the Latin exactus "exact or accurate," a form of the verb exigere — meaning "to force out or demand," like the Mob demanding its money.
