Definition
虚数 has two distinct meanings. In mathematics, it refers to an imaginary number (a number that when squared gives a negative result, like √-1). In everyday language, it can mean an unreliable or fabricated figure — a number that doesn't reflect reality. The two senses share the idea of something 'unreal' (虚).
