- Is there a symbol for finite?
I know there's a symbol for infinite. But is there a finite one?
Dumb question. What is C in this case?fresh_42 said:It is usually written ##<\infty## or if it was done better ##=C<\infty##.
Is infinity undefined in reals ?Nugatory said:How about just specifying that the number in question is an element of the reals? There are no infinite reals.
I prefer to think of them as mathematical constructs. English isn't necessary, which is good if you don't speak it.Mark44 said:Finite and infinite are both adjectives. Although there is a noun form for infinity, I'm not aware of the existence of "finity" as a word in English. If so, we have a symbol for and a word for infinity, ##\infty##, we have neither a word or symbol for its opposite.
Yes. In some cases the set ##\overline{\mathbb{R}}=\mathbb{R}\cup \{\pm \infty \}## is used. It is referred to as extended real numbers.7777777 said:Is infinity undefined in reals ?
I'm sure mathematicians prefer ##< \infty ## over those code style notations.caz said:logically
finite = not infinite = ¬∞ or !∞ or ##\infty##’ or ##\overline{\infty}##
A slightly better reference:This page references the OED and says that finity is a word.

Given the mathematical disdain for logic symbols, may we postulate a dearth of Vulcan mathematicians?fresh_42 said:I'm sure mathematicians prefer <∞ over those code style notations.

I think one has to be careful using that symbol. I have seen it mean convergence.fresh_42 said:It is usually written ##<\infty## or if it was done better ##=C<\infty##.
The symbol for finite is a small vertical line with a horizontal line crossing through it, similar to the mathematical symbol for infinity (∞) but with the lines crossed.
The symbol for finite is used to represent a quantity or value that has a definite limit or is bounded. It is often used in set theory, calculus, and other branches of mathematics.
While it is primarily used in mathematics, the symbol for finite can also be used in other fields such as computer science, engineering, and physics to represent a finite or limited quantity or value.
Yes, there is a difference between the two symbols. The symbol for finite represents a bounded or limited quantity, while the symbol for infinity represents an unbounded or limitless quantity.
Yes, there are a few alternate symbols for finite, such as the letter "F" with a line through it or the letter "N" with a line through it. However, the small vertical line with a horizontal line crossing through it is the most commonly used symbol for finite.
