One of our users was sent to a client's site to upload some work files for review. She got a message that said something like:
This website requires an HTML 4.0 compliant web browser with Javascript enabled. You are using a browser version that does not meet these requirements. It is recommended that you use either Internet Explorer versions 5.5/6.x/7.x, or Netscape version 7.x. Refer to your browser's online help for specific instructions to enable Javascript.
Yet we are using IE 7 with JavaScript enabled. So I went digging through their page to see what triggered that message and found this little gem:
function browserSupported()
{
var agt=navigator.userAgent.toLowerCase();
var agt=navigator.userAgent.toLowerCase();
var is_major = parseInt(navigator.appVersion);
var is_minor = parseFloat(navigator.appVersion);
var is_nav = ((agt.indexOf('mozilla')!=-1) && (agt.indexOf('spoofer')==-1)
&& (agt.indexOf('compatible') == -1) && (agt.indexOf('opera')==-1)
&& (agt.indexOf('webtv')==-1));
var is_nav62up = (is_nav && (is_major >= 5) && (is_minor >=5) && (agt.indexOf("gecko")!=-1) );
var is_ie = (agt.indexOf("msie") != -1);
var is_ie3 = (is_ie && (is_major < 4));
var is_ie4 = (is_ie && (is_major == 4) && (agt.indexOf("msie 5.0")==-1) );
var is_ie4up = (is_ie && (is_major >= 4));
var is_ie5 = (is_ie && (is_major == 4) && (agt.indexOf("msie 5.0")!=-1) );
var is_ie5up = (is_ie && !is_ie3 && !is_ie4);
var is_ie55 = (is_ie && (is_major == 4) && (agt.indexOf("msie 5.5")!=-1) );
var is_ie55up = (is_ie && ((!is_ie3 && !is_ie4 && !is_ie5) || is_ie55));
var is_ie6 = (is_ie && (is_major == 4) && (agt.indexOf("msie 6.0")!=-1) );
var is_ie6up = (is_ie && ((!is_ie3 && !is_ie4 && !is_ie5 && !is_ie55) || is_ie6));
var is_opera = (agt.indexOf("opera") != -1);
if (is_nav62up || is_ie55up || is_opera || is_ie6up || is_ie6)
{
return true;
}
return false;
}
Note the complete and utter lack of a check for "msie 7.0", let alone the horrible combination of and's and not's to set all those is_<browser> flags.  -Greg

It took me about 20 minutes to work out what the heck this For/Next loop was doing. The programmer must not have heard of .Split.
It takes a key from an INI file (vkeys) and if it is formatted as such:
SERVICES = Service1, Service2, Service3, Service4 ...
it puts the list of services into an array for later use..
If vkeys(lval, 0) = "services" Or vkeys(lval, 0) = "SERVICES" Then
totallength = Len(vkeys(lval, 1))
For searchstring = 1 To totallength
tempcounter2 = tempcounter2 + 1
If Mid(vkeys(lval, 1), searchstring, 1) = "," Then
servicecount(X) = servicecount(X) + 1
nodeservices(X, servicecount(X)) = Mid(vkeys(lval, 1), _
tempcounter1, tempcounter2 - 1)
If Right(nodeservices(X, servicecount(X)), 1) = "," Then
nodeservices(X, servicecount(X)) = _
Left(nodeservices(X, servicecount(X)),_
(Len(nodeservices(X, servicecount(X))) - 1))
End If
tempcounter1 = searchstring + 1
tempcounter2 = 1
End If
If searchstring = totallength Then
nodeservices(X, (servicecount(X) + 1)) = Mid(vkeys(lval, 1),_
tempcounter1, tempcounter2 - 1)
End If
Next searchstring
servicecount(X) = servicecount(X) + 1
tempcounter2 = 1
End If

It's a horror right from the first line
If vkeys(lval, 0) = "services" Or vkeys(lval, 0) = "SERVICES" Then
...what about "Services"

Release 1.01: Added support for "Services".

Dear Mr./Ms. User,
We are currently offering support for "services", "Services", "SERVICES" (based on user skill - does not know about text formatting rules, knows about text formatting rules, does not know about CAPS LOCK key) and we plan to support "sERVICES" (for users who know formatting rules but forgot about CAPS LOCK key) in future releases.
As far as we see, "serviceS" is an anomaly and it should not be considered a bug.
Yours trully,
Programming Team Leader.I have no smart signature yet...

Development team answer:
This is not a bug. All key values must be uppercase.
We are simplifying the application so services and Services are no more supported, avoiding further errors.
In fact, the check is now:
If len(vkeys[lval, 0]) = 8 and Mid(lvkeys[lval, 0], 0, 1) = "S" and Mid(lvkeys[lval, 0], 1, 1) = "E" ... and so on.
(Note, I started to write this at the same time of the last post... I think our development team is having problems of communication... who the hell tought we must support other keywords?? ).

This is an excerpt from some sample code provided in the documentation for an EFT interface
decimal divider;
divider = 10*10*10;
divider = Decimal.Multiply(divider,10*10*10*10*10);
divider = Decimal.Multiply(divider,10*10*10*10*10);
divider = Decimal.Multiply(divider,10*10*10*10*10);
Blows my mind

Never mind casting - at least he didn't use a loop:
decimal tenE18 = 1;
for (int i = 0; i < 18; i++)
{
tenE18 *= 10;
}
Still, I think I will stick to the old-fashioned, boring way:
decimal d = 1E18M;

 test your code - it saves processing time, but raises debug time - if you are able to compile it
|
|

it might have a syntax error but you can do it this way.. you can refer algorithm by corman... n compare to given algo
for (int i = 0; i < 18; i++)
{
tenE18 *= 10;
}
this one will run for 18times.. for debuging also you have to go through this loop 18 times... then how can you say algo i gave takes more time to debug.. complexity of given algo is O(n) and complexity of algo i gave is O(lg(n))....modified on Wednesday, March 3, 2010 10:37 PM

O(n) and O(lg(n)) apply to execution time, not debugging time.
There are no formulas for debugging time; it depends on number of statements, decision points, readability of code, and initial number of bugs. Your code has more than 5 bugs, it will take you lots of time to find all of them. I suggest you try and fix and run it until the result is correct.

thank you for answering to chevu - he didn't get the hint - "debug time" ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

that is completely wrong in many ways. did you try a simple example, say pow=1?
|
|
|
|
|
Is that an attempt at binary exponentiation?

run your code -> how many digits do you count?

lol - same results...
Check it:
using System;
namespace DecimalTest
{
class Program
{
static void Main(string[] args)
{
decimal divider;
divider = 10*10*10;
divider = Decimal.Multiply(divider,10*10*10*10*10);
divider = Decimal.Multiply(divider,10*10*10*10*10);
divider = Decimal.Multiply(divider,10*10*10*10*10);
Console.WriteLine(divider);
decimal tenE18 = 10;
for (int i = 0; i < 18; i++)
tenE18 *= 10;
Console.WriteLine(tenE18);
Console.WriteLine(10E18M);
Console.WriteLine(String.Format("{0:N}", Math.Pow(10d, 18d)));
Console.ReadKey();
}
}
}
who invented those nasty zero!?!

Yeah, I checked my results matched! 
I didn't check his!
