NUL

释义

'Null' means having no value, empty, or invalid. Commonly used in technology and mathematics to indicate nothing is there.

用法与细微差别

'Null' is formal and technical, rarely used in everyday conversation. Common in programming ('null value'), databases, mathematics, and legal language. Not a synonym for 'zero'—'null' means nothing or absence of value, not the number zero.
