Y'all are so uncreative.
How about `float bool` or `fbool`.
Or `fbit`...
Or what about an `fowen`? (floating oh + one)

I think it's the opposite way round: normalisation results in units being dropped. The typical, most common, definition of normalisation is value ÷ max possible value, giving a result in [0,1]. (More general definitions of normalisation exist e.g. if you rescale so the standard deviation is a fixed value, or even use non linear rescaling, that could count, but never mind all that.) The parent comment's example of "po…
Hmm when I think of 'normalizing' I don't think of dividing by a max at all - in my experience it is more taking a quantity (perhaps in English measurement) and transferring to a more 'standard' unit (say metric). In general I don't think normalization always includes a sense of being in a bounded interval. From a mathematical perspective you could perhaps say normalization is achieved by multiplying your quantity by…
Of course the literal meaning of "normalisation" is to make more "normal", and that can mean almost anything at all. Even the Wikipedia article you linked to starts with "normalization can have a range of meanings". If you have heard that word most used with one meaning and I have heard it most used with another meaning then that doesn't invalidate either of those definitions.
The Wikipedia article you linked to gives two very broad definitions in the lead. The definition covered in the first paragraph is "adjusting values measured on different scales to a notionally common scale", which seems to be what you're talking about.
The definition covered in the second paragraph is "the creation of shifted and scaled versions of statistics", in particular "some types of normalization involve only a rescaling, to arrive at values relative to some size variable". I'm not comfortable with the use of "of statistics" in that second definition: the very first example is in the article standard score [1], which is about a rescaled element of the population, not a rescaled statistic. In any case, outside of statistics, a rescaling is a common meaning for this word, and a rescaled statistic is clearly just a special case of this. I think it was clear from the context that we were talking about this meaning originally. By far the most common case of this is a linear rescaling (including translation) to [0,1] but I was already up front that this is just a special case.
As for your sigmoid comment, I may have misunderstood but it sounds like you're saying that if you have a variable in the range in [0,1] then it can be described as the result of a sigmoid function. My objection to this is the same as my original objection to calling such as variable "normalised": it is a confusing variable name to use unless you actually did get it by applying a sigmoid function to something, not just because it holds a value that could hypothetically be obtained from a sigmoid function (but you didn't).

#243Looks like it could be a "probability".
Re: A word for a value between 0 and 1 (inclusive)
#244I don't think this is a naming issue at all. In the provided example, 'Accuracy' is the correct name for the parameter, as that's what the parameter represents, accuracy. The fact that accuracy should be given as a value in an interval from 0 to 1 should be a property of parameter type . In other words, the parameter should not be a float, but a more constrained type that allows floats only in [0,1]. EDIT: Some of yo…
Looks like it’s actually possible to string something like this together in Python; custom types are of course supported, and you can write a generic validation function that looks for your function’s type signature and then asserts that every UnitInterval variable is within the specified bounds.
You’d have to decorate/call manually in your functions so it’s not watertight, but at least it’s DRY.

Unfortunately, creating a constrained type like this isn't easy (or even doable) in all programming languages. Fortunately, my preferred programming language, Raku, makes creating this sort of subset trivially easy[0]: subset UnitInterval of Real where 0 ≤ * ≤ 1 [0]: https://docs.raku.org/language/typesystem#index-entry-subset...
In C, I wonder if you could do something with functions and macros?
Say you need to represent velocity in a transportation simulation. You could have a function, velocity, that looks like this:
double velocity(double v, char * of_what)
double v_jogger = velocity(8.0, "human");
double v_car = velocity(65.0, "city car");
You probably couldn't reasonably use this everywhere that you would use actual constrained types in a language that has them, but you could probably catch a lot of errors just using them in initializers.

#247Does anyone know of a good site for these kind of questions other than the English stack exchange. I frequently run into programming related naming issues (who doesn't eh?). But I struggle to find accurate search terms to help answer them...and the results are usually downed out by non-technical related language Q&A's E.g. I was trying to name a table yesterday that would store events related to boxes, pallets, conta…
> events related to boxes, pallets, containers and vessels
Think about why these 4 things are of interest. What aspect of them is it you're working with?
If that aspect has a name, that might be the basis if a good name that reflects the purpose of your code.
Re: A word for a value between 0 and 1 (inclusive)
#248How about just oTo1InclusiveVal ? I know very simple, but would get the job done ?
we can put underscore before the 0 so that it is a valid name

#249Earlier quoted context omitted.
What I was taught in school is that "percent" doesn't refer to 0 - 100, it refers to 0% - 100% which is equal to 0 - 1 (not really a conversion, actually equal). As 0% and 100% aren't floats (they're more like formatted values), seeing AccuracyPercent in the question had me thinking there was nothing more accurate.
So if you build a tax calculator and add a field with the label "Please add your tax rate in percent" you expect people to enter a value between 0 and 1?
No, but you're defining a unit here; I'd expect people to put in values as 0..100 with unit being percent. So if a person puts in 20, and you'll want to multiply it by 3, you'd not expect 60 as end result; you'd expect 60% which is 0.6
You're still raising valid point with the ambiguity - if I were to see a variable named `population_percentage = 0.01` I'd still need to ask the author if the intended value here is 1 or 0.01, which I'd say disqualifies this naming.

Is there an example, in any language, showing how you would represent this at the type level? I can’t see how you would do it.
In Elm (and many other languages, I assume, I'm just most familiar with Elm) there's a pattern called "opaque data type". [0] You make a file that contains the type and its constructor but you don't export the constructor. You only export the getter and setter methods. This ensures that if you properly police the methods of that one short file, everywhere else in your program that the type is used is guaranteed by the type system to have a number between zero and one.
