But because many websites and other Internet services don't offer the entire range of possible characters, substitutes for full mathematical notation are often used for convenience.
When it comes to decimal numbers like a string of nines to the right of the decimal, you can either round up to a solid 1 or accept that adding more nines will approach but never reach 1.
That is more or less correct regarding the ellipsis in mathematics. It is generally used to signify that a number or trend continues. If it terminates, the last term is written; if not, it ends with the ellipsis. Such examples include infinite decimals (rational or irrational), sequences, series, recursive functions, and sets.
