Trying to convert "1.12" to double :
Dim MyDouble as double
MyDouble = cdbl("1.2")
I obtain the following error message :
"La conversion de la chaîne "1.2" en type 'Double' n'est pas valide."
"Conversion of string "1.2" to double is invalid"
I have setted my international parameters in order to have the point (.) as my decimal setting. My other software on my computer understand "1.2" (Excel, Simply accounting...).
I am using Visual Studio 2005 and VB as my coding.
Please help me.
Regards,
Pierre

Have you tried: -
Dim MyDouble as double
-
MyDouble = double.Parse("1.2")
-
Yes I did and it does not work as well.
Thank you for trying to help.

How about : -
Dim MyDouble as double
-
Dim nfi As New System.Globalization.NumberFormatInfo()
-
nfi.NumberDecimalSeparator = "."
-
MyDouble = Double.Parse("1.2", System.Globalization.NumberStyles.AllowDecimalPoint, nfi)
-
Hi PLater,
It partially works.
I do not have an error message and my string is converted to a double value, but this double value is 1,2 instead of 1.2.
My objective is as the following :
1- The possibility for the user to enter a value like 1.2
2- Save this value in a SQL Server field which is configured as real
SQL server does not accept 1,2, it accepts 1.2. When I convert 1.2 to double, if I obtain 1,2, it does not work. Consequently, the double value obtained must be 1.2.
Do you see a solution ?
Regards,
Pierre

Double values are not stored with a "." or a "," it's all how you present them with .ToString() and such.
either use a stored procedure that will take a double as a double, or change your myDouble.ToStri ng() to something similar to what I used for the .Parse() so that it prints using a "." instead of a ","
Hi Plater,
With your code lines + your comments, I succeeded.
Thanks a lot for your help.
Regards,
Pierre

Hi everyone,
A basic one here, I think. I haven't found the pattern yet, but
sometimes when I cast a variable to another type using the "C" style cast
operator the compiler refuses to play along. It says it's an invalid cast.
However, if I use the Convert.ToInt32() method (for example) things will
work. At least, that's how it appears to me.
Could someone explain when to use old-style parenthesized casts vs. the
Convert() methods?

I have tried to use FormatNumber() to convert a very large double type
number to String format, however, the result seems not correct, is there any
limitation for using FormatNumber() function?
For example, I write the code shown below:
Dim DblA as double = 999999999999999.12
Dim VarA As String = FormatNumber(DblA)
The result of VarA contains value "999999999999999.00" instead of
"999999999999999.12".

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.
