non-recurring part (of the decimal)
The most natural way to express it IMHO.

Thomas Walker
: I agree with Charles that it's probably not a good idea to use "prefix"; so if you need to say something about it, I think "non-recurring part" is clear & unambiguous, & not too long.

finite part
The "periodo" is called the repetend, but there doesn't seem to be another term for the digit or digits before the repetend.
"the figures before those that repeat are called the finite part"
https://books.google.es/books?id=bl4UAAAAQAAJ&pg=PA70&lpg=PA... (a book published in 1818)
"the decimal before the repeating figures is called the finite part of the decimal"
https://books.google.es/books?id=5XwBAAAAQAAJ&pg=PA150&lpg=P... (this one's from 1836)
For repetend see
https://en.wikipedia.org/wiki/Repeating_decimal
Here somebody asks what it is called and an answerer coins the term "prefix", but clearly doesn't know any official term. I wouldn't use "prefix".

I can't find anything else for this.

Cheers, Neil ;) Well, maybe, though I have to say I've never needed to say this before, and apparently mathematicians don't need to say it very often since they haven't even invented a proper word for it.

non-recurring digits
As the question stated, there may be one or more non-recurring digits before the repeated portion of the number.
Discussion
And, yes, "prefix" is just barbarous.
I don't think tautology applies here - that type of construction is common in Math definitions.
