In mathematical literature I came across an equation where a doublestruck E symbol is used (last equation in the picture below).
I don't have the faintest clue what the doublestruck E means. I'm guessing it denotes some kind of function? I've checked the entire document and it offers no explanation what so ever.
Does any of you have any idea what the doublestruck E means?
Thanks for the reply Plato. Yeah, the way it's typed it could even be just a variable (although I doubt this, the document does have a pretty extensive nomenclature and there is no listed in it).
I was kinda hoping that would be a commonly accepted (but not often used) notation for a certain function.
Okay, don't leave us guessing- what is the "Entier" function?
Well, it turns out I can use "google"! "Entier" is the French word for "integer" and the "Entier function" of x is the "integer part" of x- the same as the "floor" function which returns the largest integer less than or equal to x.
