Is Decimal (correctly-rounded arbitrary precision decimal floating point arithmetic) fixed-point, floating-point or something else?

The Decimal data type I am referring to is GNU MPFR(, or libmpdec (

I have been searching for information about decimal for days and learned that you can use fixed-point (int + scaling factor) to represent a non-int real number, but I have looked into the above two libraries, which doesn’t look like fixed-point. Instead, they refer to the implementation as (correctly-rounded arbitrary precision decimal floating point arithmetic).

The information online is very limited (or there are something obvious I have missed).

I would like to know more.

Calculated Column with IF ISBLANK, else if “ABC”, then return “XYX”

If [OH:Subsample ID] is blank, OR if it contains “ABC”, then the calculated field should return result “XYZ”… no idea how to put that into syntax…

I can get two separate lines, but can’t get them combined into one command line.. =IF([OH:Subsample ID]”Header Line”,”Audit”) =IF(ISBLANK([OH:Subsample ID]),”Audit”)

Can I make an object, so that when the characters touch it they are teleported somewhere else?

I want it so I can teleport characters to the top of a tower in D&D 5e. They will then battle their way down the tower. My idea is that they touch an object and it teleports them there. Is this a thing, or is there a better way of doing this?

I want to use this for an idea I have for a 1 off adventure: the party is told that farm animals are going missing. They find out it’s from a teleport masked as an item (I haven’t decided what item). They use the item to teleport to where they are going, find they are food for a tower of orcs. They fight the orcs and face a wizard at the end who made the teleport item.

sweetalert2 no funciona o no responde en el if o else

Hola estoy implementando un sistema de registro de mascotas y quiero que al momento de enviar el formulario envíen un mensaje de éxito, estoy utilizando sweetalert2, he logrado hacer la condición, pero al momento de poner el código de sweetalert2 en el if no me responde, me gustaría me ayuden.

Could a spellbook be destroyed/emptied by being viewed by someone else?

In my first ever game of D&D (this was many years ago), I joined an existing game, and at the table, I was sitting beside a player playing a wizard (or “Magic User” to use the parlance of the time). The player had a little notebook to represent her spell-book, so at one point out of idle curiosity, I picked it up and flicked through it.

Another player at the table jumped up and pointed, shouting out with glee (we were kids) that I had read the wizard’s spell-book, as it turns out that if anyone other than the wizard herself looks at it, all the spells would vanish from the book.

So the GM declared that this indeed is what happened, she would have to start a new spellbook, collecting her spells all over again and the wizard player spent the rest of the session understandably unhappy, glaring & cursing at me and so on.

Has this ever been a rule in D&D?

In all my years of playing (OD&D – which I believe this was, AD&D 2nd Ed, 3, 3.5, etc.) I have never come across a rule like this. I suppose it’s possible she had a curse or something but in the ensuing argument this was never mentioned – they seemed to be making out that it was just a rule about spellbooks, and that I should have just somehow known not to do this.

Estoy validando el peso del electrodomestico:

if (this.peso >= 0 && this.peso < 19) {          this.valor_extra += 10;      }else if (this.peso >= 20 && this.peso < 49) {          this.valor_extra += 50;      }else if (this.peso >= 50 && this.peso <= 79) {          this.valor_extra += 80;      }else if (this.peso >= 80) {          this.valor_extra += 100;     }  

lo he visto mil veces y esta bien validado, pero por alguna razon el no valida las demas opciones, simplemente le agrega 10 aunque el peso sea mayor o igual a 20

Who else wants to try the french market for digital products?

Hello, there's a clickbank-like in french, it exists since 2007.
I use it since 2012, it pays without delay once a month by paypal or by check in euro, or by bank wire transfert.
Even if you don't speak french you can be in my club where I share a % of each members (and non-members who use my tools) commissions between all paying members.

Here is my club :

And here are my earnings for the past 12 months with 1TPE alone :…

Who else wants to try the french market for digital products?

if (a) {b();c();d();} else {c();} – prevent duplicate code c(); [duplicate]

This question already has an answer here:

  • Avoid Code Repetition in Condition Statements [duplicate] 1 answer

I’ve got the following scenario:

bool bWantToWait = getRandomBool();  if (bWantToWait){     std::future<bool> bSuccesfullWait = this->doStartWait(); }  //lots of lines of code //even more lines of code //doExecuteSomethingWithAsyncCallback  if (bWantToWait){     return bSuccessfullWait.get(); } return true; 

Now of course bSuccesfullWait is out of scope in the second if statement, so this won’t compile. But basically what I want is that doStartWait() “initializes” a wait. I don’t want to initialize this wait if I don’t have to, as it’s relatively resource intensive.

An example application for this would be networking. this->doStartWait(); would open up a port, and return a future that returns when a message comes in. this->doExecuteSomethingWithAsyncCallback(); would send something to a different PC, which would then return a message on the port opened in this->doStartWait();. You’d want to make sure that the port is opened before sending a message, so you don’t miss the reply.

What I’ve resorted to is the following:

bool bWantToWait = getRandomBool();  auto fnExec = [&]()->void{     //lots of lines of code     //even more lines of code     //doExecuteSomethingWithAsyncCallback };  if (bWantToWait){     std::future<bool> bSuccesfullWait = this->doStartWait();     fnExec();     return bSuccessfullWait.get(); } fnExec(); return true; 

The downside of this approach is that the code is not in chronological order any more, and that ideally I’d like to prevent the overhead of function calls. An alternative would be to make a std::future<bool>*, or std::unique_ptr<std::future<bool>>, but that also adds overhead. The least overhead method would be raw pointers, but that still uses the heap instead of just the stack.

Am I missing an obvious solution to having a variable “stay in scope” over two if statements?

Can a character use her movement to help someone else stand up? [duplicate]

This question already has an answer here:

  • Can you help a prone character to stand up? 3 answers

Standing up takes half your movement, and you can also interact with one object for free during your turn. Neither of these things indicate whether or not you can help someone else stand up on your turn. If you can knock someone prone or drop prone, then it makes sense that you would be able to help someone else stand up. Do the rules allow this?
