What is a synonym for exactly?

I'm curious, could you please clarify for me what another word or phrase might be used to describe the concept of "exactly"? I'm looking for a synonym that conveys the same meaning of precision, accuracy, or specificity as the word "exactly" does. Perhaps there's a term that encapsulates the idea of something being precisely as stated or described, without any deviation or ambiguity. I'd appreciate any suggestions you might have.
