Hi,
I noticed when migrating a 2002 application to 2003 that the system changed
to a different usage for pow(2,-15).
In 2002, it used double pow(double,doub le).
In 2003, it is using double pow(int,int).
You may note that pow(2,-15) and pow(2.0,-15.0) give different results.
math.h is included.
Is there some way to force studio to not use the complex prototypes?
math.h is the only include file being used. Why is it even linking to the
others?
Is there a project option to control that?
I'd rather not go through and verify every math operation in this code for
prototype changes..

The compiler is going to choose the function that has matching argument types, if one is present,
since that's a C++ requirement. If pow(int, int) has been added to <math.hsince 2002 then it's
going to choose that for 2, -15. I don't see how any project options could change the language rules
just for math functions, and I don't see any #ifdefs in the header for excluding the new functions
in C++. I suspect that you're going to have to pass doubles if you want pow(double, double) or
compile it as C instead of C++. My knowledge of 2003 (and 2002) is very limited, however.

Why doesn't this work?
>>> import math
>>> math.exp(1j*math.pi)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: can't convert complex to float; use e.g. abs(z)
The expected answer, of course, is -1.

Hi All
Wondered if you could help.
Basically I have 2 tables that contain all the data I want for my report,
but I need to put it in a particular way and I need to display it in an ASP
page so my queries got to be manual rather than an MS Excel/Query 'munge'.
To be honest, the report itself is very basic, so hopefully my ramble will
make sense. I need to report that shows 6 columns at best, 4 columns if

Hi all
I've taught myself C# 2002 using VS.NET 2002. I've recently brought myself
an ASP.NET 2003 book. I will work through this ASP.NET 2003 using VS.NET
2002 and C# 2002. I don't fully understand the differences between the VS.
NET 2002 and VS.NET 2003.
Will I restrict myself in any way learning ASP.NET 2003 but only using VS.NET
2002 and C# 2002?

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
