Timings... sometimes there are almost too many ways to do the same thing.
The only significant findings I see from all the below timings is:
1) Integer math is generally fastest, naturally. Bigint math isn't much
slower, for integers that all fit within an integer.
2) Converting float to varchar is relatively slow, and should be avoided if
possible. Converting from integer to varchar or varchar to int is several
times faster.

Hallo,
It is know issue that due to the fact that computer has to store the real
numbers in limited set of bytes, thus causing a minor imprecision from the
decimal value that likely was stored. I don't know, how dotnet framework
stored doubles, but it's certain, that if I store, say, 1.234567 in some
real variable, it is stored in memory like something close to
1.2345670000000000000003454786544 or...

Hi,
I'm writing a program using VB.NET that needs to communicate with a DOS
Pascal program than cannot be modified. The communication channel is through
some file databases, and I have a huge problem writing VB Double values to
the file so as the Pascal program can read them as Pascal Real values.
I've managed to find the algorithm to read the Pascal Real format and
convert it to a VB Double, but I cannot figure out the opposite...

Hi, now that in .NET everything is on millimeter, I was wondering how
can one convert Pixel to Millimeter and any user's screen/monitor. I
saw the following code on how to convert pixel to millimeter. It's
done on pascal/delphi, but can be very easily read & converted to VB
..NET.
However my question is what is the difference between "real"
millimeters and "logical" millimeters?
The source of the code is in the following thread:

I am evaluating a request for an alternate version of itertools.izip()
that has a None fill-in feature like the built-in map function:
>>> map(None, 'abc', '12345') # demonstrate map's None fill-in feature
The movitation is to provide a means for looping over all data elements
when the input lengths are unequal. The question of the day is whether
that is both a common need and a good approach to real-world problems.

Good day everyone. This sounds like a stupid question, but I became
just curious yesterday, and I looked up several textbooks. However, no
textbooks on computer language (that I have ) mentioned this. So I am
asking to you, gurus...
Is there any particular reason to call 'float' instead of 'real'?

Folks,
Can anyone thow some clarifying light on the following?
I have come across a column with the same name and same data contents
defined on different tables, on some the column is defined as a FLOAT
on others it is a REAL.
(Don't ask me why, it's inherited, legacy and due for removal once we
have absorbed all the good bits into the data warehouse). .

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
