Why does this not work, and how should i do this convert in stead:
string x = double.MinValue.ToString();
double y = Convert.ToDouble(x);
i get this exception:
An unhandled exception of type 'System.OverflowException' occurred in mscorlib.dll
Additional information: Value was either too large or too small for a Double.

hi all.
In my program I need to convert a double number to stringrepresentation in fraction format and vise versa. For example,convert 0.75 to string "3/4" and convert string "1/2" to 0.5.The class will only need to handle numbers that increment by1/32. That is 1/32, 2/32, 3/32.... 31/32, 1. If the doublenumber is 0.28 which is between 1/4 and 9/32, the string shouldbe 9/32(go with the bigger number).
TIA

Hi All,
I'm am looking to convert a currency string (e.g. "$1,234.56" to a
double value).
It appears this will work:
double val = Convert.ToDouble(Double.Parse("$123,456.78901",
System.Globalization.NumberStyles.Currency));

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...

In VB.NET, when I use System.Convert.ToDouble(string Val) to convert a string
variable to double variable, I got something interesting:
Dim stringVal As String = "101.01"
Dim doubleVal As Double
doubleVal = System.Convert.ToDouble(stringVal)
Msgbox (doubleVal) will return 101.01
but......
Dim stringVal As String = "101.00"

In my code i use the text from a textbox and convert it to a double value.
I was using Convert.ToDouble() but i'm used to convert comma to dot.
This way i can assure the text is correct.
However it seems this convert is determined by the local settings and comma
is indeed used as decimal separator.
Is there another way to convert a dotted value to a double variable?
Like 1234.5 and not 1234,5

Hi!
In germany, norway and France(?) we are using ',' as decimal separator
and it always messes up when you convert a double to and from a string
where the interface expects double values stored as string is using '.'
What parameter shall I use in double.ToString() to ensure that the
outputstring always are using '.' as separator without thousand sep,
and what parameter shall I use to convert double to Double.Parse() or...

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:

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,...
