Is there a symbol for "probably equals" ?
An example would be A probably equals B.
An example would be A probably equals B.
Depends on what probably means! If you do not know, then the question mark makes sense: ##\stackrel{?}{=}##. If it is equal up to finitely many exceptions, or if the exceptions are otherwise a set of measure zero, then you can write ##{=}_{a.e.}## for "almost everywhere". Thus it all depends on what is "probably" to you. If you actually have a probability, then it is ##P(x=a) = c\% ## with possibly an error margin ##\pm e\%## behind it.John Bartle said:Is there a symbol for "probably equals" ?

I don't read thatJohn Bartle said:@jedishrfu
Thanks. I'd rather have a probably equals symbol but I think I might just settle for the ≟ or the a.s. notation.

I'm not real good with math in general, and I know even less concerning probability and statistics. What notation, for example, would you think makes sense for the statement:
cat very likely equals animal
I know cat is a subset of animal, but most people say a cat IS an animal also. I also want to point out the fact that it is only very likely an animal because nothing/not much is certain.I would just go with cat =a.s. animal
StoneTemplePython said:One is that equalities run both ways so you need to be careful... I don't think people would claim an animal is a cat.
StoneTemplePython said:You have the right idea with subsets. Why not ##\text{cat} \subset \text{animal}## with an asterisk saying that you are highly confident of this?
I can't find that symbol. Can you tell me where I would find it?jedishrfu said:A better one might be a % over the equals
A ball is a subset of a sphere. They are not equivalent.John Bartle said:An example would be "ball necessarily equals sphere"
John Bartle said:or maybe "truth necessarily equals (not falsity)"
A variable.John Bartle said:Is there a symbol for "probably equals" ?
If A and B are not variables then A doesn't equal B. You can't compare two values without reading them, that is guessing and trying to compare. Your "probably" is selecting the right data type in software dev terms.John Bartle said:An example would be A probably equals B.
jedishrfu said:@John Bartle you have been pursuing this notion for several posts. However it appears that there is no such symbol.
jedishrfu said:It wasn’t against the rules, I was worried that you were pursuing something that just doesn’t exist yet and maybe never will. We alll get stuck in this notion of there has to be something and if I search long enough I’ll find it.

slappmunkey said:I was actually talking about this with a friend yesterday.
We were discussing about 0^0 and how it "probably" be 1. Even the maths implies that it would eventually be 1, but without an infinite number of equations it fails.
For instance 0^google would still be 0, because Google is still a countable number.
But when doing 0^0 , the closer you get to powering 0 by 0, the closer your answer comes to 1.
So if you do find a symbol tell me so I can apply it to 0^0 (probably)= 1

I like how you phrase that in a question like it isn't obvious... I'm not trying to be rude but you clearly see it's a typo, you clearly know what I'm talking about... So is it really that worth it to nit pick an error that was autocorrect anyways?PeroK said:

It would have been better to just simply state that I made a typo, not ask me like I'm too stupid too see... Kind of insulting. I'm a grown man, if I make a typing error (on my phone God forbid) just tell me, you don't have to be cynical about it.
I pwned guy once who was certain it was spelled Google. He'd never known they were two different words.PeroK said:A lot of people, for the obvious reason, think that the number is spelled the same as the engine. I thought it was worth pointing it out.

In scientific notation, "probably equals" is a symbol used to indicate that two values are likely to be equal, but there is a small chance that they may not be exactly equal.
Yes, the symbol for "probably equals" is a combination of the equal sign (=) and the tilde (~) symbol, written as "≈".
"Equals" in scientific notation indicates that two values are exactly equal, while "probably equals" indicates that there is a small chance they may not be exactly equal.
Yes, "probably equals" can be used in all scientific fields as it is a universally recognized symbol in scientific notation.
Yes, there are other symbols that can be used to indicate a similar meaning to "probably equals", such as "≅" (approximately equal) and "≃" (approximately equivalent).
