View 2 RepliesI'd like to convert a string which contains a decimal number into string that contains the binary value, the octal and the hexadecimal value of that decimal number.Afterwards I also like to convert a string containing a binary, octal and hexd. number into a decimal string.Basically I'm looking for the functions:
dec2bin
dec2oct
dec2hex
bin2dec
oct2dec
hex2dec
I'd not prefer to rewrite a function, I'm sure the framework must have these functions already.

View 1 RepliesI am trying to convert information stored in a file to a decimal (or ASCII) format, then write the contents of that file to a new file.
What I have is a list of files that are generated from a cash register. The documentation that was provided to me says that this particular file I am trying to work with has a length of 6, a width of 6, and that it's BCD type.
I've done quite a few google searches and can't seem to find a good solution. I know BCD numbers should be stored as 0000 format. But the problem I'm getting is when I read each part of the file (using my sr.read) I'm getting full numbers..and I am expecting the 0000 format. I'll get a 0, 0, 0, and then all of the sudden I"ll get a number that's 65,000..then I'll get a 34...and there doesn't seem to be any
I'm sure I'm doing something incorrect here, my knowledge of reading HEX, BCD, etc. is very minimal. I'm guessing it has to do with using a filestream, so I can use the fs.ReadByte() method..but when I tried that my program was literally chugging along for several minutes with no sign of ending.[code]...

View 8 RepliesLet's say I want to convert a Double x to a Decimal y. There's a lot of ways to do that:
1. var y = Convert.ToDecimal(x); // Dim y = Convert.ToDecimal(x)
2. var y = new Decimal(x); // Dim y = new Decimal(x)
3. var y = (decimal)x; // Dim y = CType(x, Decimal)
4. -- no C# equivalent -- // Dim y = CDec(x)
Functionally, all of the above do the same thing (as far as I can tell). Other than personal taste and style, is there a particular reason to choose one option over the other?
EDIT: This is the IL generated by compiling the three C# options in a Release configuration:
1. call valuetype [mscorlib]System.Decimal [mscorlib]System.Convert::ToDecimal(float64)
--> which calls System.Decimal::op_Explicit(float64)

The Database Field has the DataType of decimal(10,2).
I have tried converting it to decimal, string, int, float in the application, but once it saves, gives the same error.
I know it is because of the database field having the type as decimal. But I cant stop the entire application, just so I can change the data type of the field.
How do I save it without getting this error? How do I control it from the application?

How can I only add the decimal part of a number to another one?
example: if a number is A = 10.25
Then X = 30
Y = X + 0.25 (Here it added 0.25 which the decimal only NOT 10.25)
Another example, If X = 16.35, A = 102.001
Y = 16.351
I am attempting to take the decimal places of a given input, round it so there are only two decimal places, then change it to a whole number. So far I have been able to remove the integer part of the number, leaving only the decimal, but the other procedures are eluding me. Here's what I have so far: (VB 2008)
Private Function DecimalNumber(ByVal number As Double) As Double
Dim Input As Double
Dim SubtractNumber As Decimal
[Code]....
That code returns the decimal part of the input just fine, and I thought maybe multiplying it by 10 would work....but obviously you run into problems when there is more than one decimal place.
I have class representing a unit of measure with a Decimal as the numeric. Just to simplify things for this example, let's say I'm representing centimeters. I'd like to implement a ToString() method for this class. The thing is, if the numeric value is a whole number I'd like to just display the decimal as an integer. Otherwise, I'd like to keep it as a decimal. So, for example, 10.5D centimeters would display as "10.5cm", but 7.0D centimeters should display as "7cm". I'd like this to be fast and simple to read. I have a working solution, but it seems like there should be a better way.Here's a contrived example showing my first crack at it:
Public Property Units As String = "cm"
Public Property NumericValue As Decimal = 10.5D
Public Overrides Function ToString()
