Comma's in numbers.

[Opcode]

Pretty self explanatory here. I am sure it wouldn't take much for the compiler to just ignore them. It's just too easy to get larger numbers like exampled below mixed up.

Code: Select all

100000000 -> 100,000,000

Of course you'd probably have to remove it from the line continuation feature.

[STARGÅTE]

The comma is the separator for parameters in procedures!
What does the compiler in your idea here:

Code: Select all

Procedure Test(a, b=0)
	Debug a
	Debug b
EndProcedure

Test(123,456)

is 123,456 a whole number? Or Parameter for a and b?

[PB]

No programming language in the history of the world has ever had commas for numbers,
probably because commas aren't used to separate numbers in all languages worldwide.
Some use periods, some just dots, some use apostrophes, and some just use spaces.
And China separates every 4 digits, not every 3. Here's some information about it:

If you want something easier on your eyes for large numbers, why not help yourself?

Code: Select all

Procedure EZ(num$)
  ProcedureReturn ValD(RemoveString(num$,","))
EndProcedure

; Add 100000000 and 222222222 together:
Debug EZ("100,000,000")+EZ("222,222,222")

[Tenaja]

Code: Select all

Procedure EZ(num$)
  ProcedureReturn ValD(RemoveString(num$,","))
EndProcedure

; Add 100000000 and 222222222 together:
Debug EZ("100,000,000")+EZ("222,222,222")

Wow, talk about code bloat! Might work for an "occasional" number, but I certainly would not use that for numerous numbers.

Anyway, I have a compiler (not for PCs) that allows the underscore anywhere in the middle of a number. Comes in handy for binary, that's for sure. Syntactically, it works because the only other time an underscore can be next to a digit is if both are part of the same identifier name.

HLA (high level assembly) does that.
The ability to space out big decimal numbers, or the byte/words components in binary and hex numbers is really helpful.
If I ever had to write a language I would put this feature in it for sure

> Wow, talk about code bloat!

Actually, that sort of "bloated" code is needed any time that you
need to convert "normal" numbers to plain. Say you have a finance
app that needs to convert a table of numbers like "$1,234,567.00"
to just 1234567... how are you going to do it without a procedure?

HLA (high level assembly) does that.

Euphoria 4.x ( which is a Basic-like programming language, not a drug ) allows it as well.

Agreed.

May be there is a way to do something like popping tool tip? Like this:

[PB]

That's a nice idea, Michael; but which character are you going to use?
As I showed above, commas aren't used in every language of the world.

Underscore '_' is a good idea. Because numbers can't contain it. If a number is started (at parsing), ignoring any underscores would be possible.

[PB]

I'd prefer no numbers be touched, anyway. Are we coders or not?

[Danilo]

So you meant locale system setting for a tooltip? 1,000,000 or 1.000.000?

Thought you meant code like: x = 1_000_000
because it should be possible from a point of a language parser.

Thing is, PB is fixed to english notation. It already uses points '.' for floats,
whereas a german parser would use comma ',' for floats. International users
are used to the english notation, so no problem (If, While, Repeat, Until, ...everything English anyway).
PB uses english syntax, and ignoring underscore in numbers should be possible.
So 1_000_000 becomes 1000000, and 1_0_0_0 becomes 1000.

Just use a macro:

Code: Select all

Macro Num(a=,b=,c=,d=,e=,f=)
  a#b#c#d#e#f
EndMacro


Debug Num(1,000)
Debug Num(1,000,000)

[Danilo]

Just use a macro:

Code: Select all

Macro Num(a=,b=,c=,d=,e=,f=)
  a#b#c#d#e#f
EndMacro


Debug Num(1,000)
Debug Num(1,000,000)

Nice idea, if you want to use comma ',' as thousands separator (english notation).

[blueznl]

Well, we're supposed to use the 100.000.000,00 notation here in NL, and I hate it!

But to be honest, I would have no problem with the 100_000_000.00 variant. Not that I need it though, it just wouldn't bother me
