Re: Issue-#151 Extending the domain of Math.ArcTan2
2 - What is the significance of your 922…295 number; can you spell it out? It is the largest number that causes the assertion to fail. 9223372036854775295. is the smallest number that passes the assertion. Note that only approx the first 16 digits of a 64-bit REAL number are reliable so attempting ...

Re: Issue-#151 Extending the domain of Math.ArcTan2
The following is a message that I received by email from Robert: Chris - can you post this for me please. I don’t have access to a computer (or my passwords) at the moment, so expect only superficial remarks. Josef: 1 - Sin looks like an improvement. Why are you comparing ABS (x) with -2…. ? 2 - Ple...

Re: Issue-#151 Extending the domain of Math.ArcTan2
The solution I prefer here is CONST maxLongInt = 9223372036854774784.; (* This is the greatest representable REAL <= MAX (LONGINT) *) ... IF x > maxLongInt ... I don't believe this will work as you would like it to. Try running this: MODULE TestLongInt1; CONST maxLongInt = 9223372036854774784.; (* ...

Re: Incompatible assignment
Why should one be forced to add the "syntactic sugar" You are not forced to do that. It is perfectly adequate to declare both variables in the same list: MODULE Anonymous; VAR a: ARRAY 3 OF REAL; b: ARRAY 3 OF REAL; c, d: ARRAY 3 OF REAL; BEGIN c := d; (* OK *) a := b END Anonymous. Refer...

Re: Files->Open under Windows 10
I just found the answer in a LabView forum:
"Double-click in the title bar area, you must have done that at some point to get it into full-screen mode."

Re: Directory or Folder exists?
Hmmm... Looking at the source code (Files.This and Files.NewLocator) It appears that it doesn't care if the folder exists or not - it only returns non-zero if the first character of the filename is "\" or "/" and the second is character is not "\" or "/": \\Te...

Re: FPU Register Accuracy
I'm not an expert on this subject but before somebody goes too far down the path of enhancing the 80-bit x87 capabilities of BlackBox it might be worth taking a leap ahead and consider using the 128-bit capable SIMD instructions instead: The x87 FPU instructions are executed by the so-called "...

Re: 8pt vs 9pt vs 10pt Arial
then understood that this should be the choice of people. Absolutely - and everybody will have a different preference. If you try to make the choice for them, for every user that you please there will be another who you displease. As I said previously, if it is really that important an issue, promp...
