I am currently writing a very specific graph of a function implementation. The graph can have min/max values e.g. $134$ and $1876$ respectively. I'm calculating "nice" numbers. For min/max they are $100$ and $1900$ respectively.
Is there a commonly used name for such a number?
I believe they are called multiples of $10$ [exclamation mark,exclamation mark,exclamation mark]

They're exact multiples of powers of ten; they're also rounded to fewer significant figures. The benefit is to rapid human interpretation of annotation.
I haven't heard of an established term for such a pair, but "reduced precision bracket" might be a good descriptor.
