Inexact means not exact: close, but not right down to the last bit. A number can be inexact, a translation can be inexact, a memory can be inexact. It does not usually mean “completely wrong”; it means “not precise.” Teachers, scientists, and careful writers use it when they want to be honest that a figure or a wording is only approximate. It is a quieter word than “wrong,” and cooler than “sloppy.” People also talk about an inexact science — a field that cannot give you a perfect, neat answer every time, because real life will not sit still for a ruler. Though actually, calling something inexact can sound polite when the speaker really means “this is too rough to trust.”

不精確的；不準確的（多半不是「全錯」，而是「不夠精準」）
