View 1 RepliesC# - Globalized Custom Number Formatting - Variable Decimal Points?
May 5, 2011I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?

Round And Format A Decimal Correctly?
Nov 23, 2010I'm trying to get my decimals to display with four decimal places. The DB rounds my number to 4 decimal places, but it returns the number with trailing 0s (due to the decimal precision of the field), so something like 9.45670000.[code]...

May 14, 2011I'm creating a maths program and when it comes to division it's giving me .34216 as answeres which isn't what I want.I was thinking declaring the textbox the answer appears in as a single.It's not working out though and it's still using decimal points.I was told by my teacher to declare it as an integer so I tried that too, it's not working out also. I figured based on the code, I would be declaring array3() as the single or integer since that's the textbox the answer will be output into. [code]

RoundUp Function - Which Will Round A Number UP To The Specified Decimal Precision
Apr 29, 2009I need a function which will Round a number UP to the specified decimal precision, exactly the same as how Excel's RoundUp function works:
Roundup(dblVal, intDecPlaces)
So I need the following:
Roundup(0.896523, 4)
would return
0.8966
However, everything i've tried/found simply rounds to the nearest whole integer, or returns a normal rounded value, hence the above would return
0.8965
I've tried the following:
Math.Round(dblval, intPrecision, midpointrounding.awayfromzero)
' and
Math.Round(dblval, intPrecision, midpointrounding.toeven)
And even custom functions, such as:
Public Function RoundUp(ByVal varValue As Object, _
ByVal iNum As Integer) As Double
'ignore the data types here, I was playing to see 'if changing any of the data types would swing 'the results (knowing full well they wouldnt make 'a difference, thats how fed up with this I am!)
Dim lNum As Long, xVal As Double, xVar As Object
xVar = Fix(varValue)
[CODE]...
I've even looked at converting this to a string, looking at the Xth decimal place, and incrementing it up by 1, then converting it back to a double, while this works (sort of) it seems to be a very roughshod way of doing it, and I'd rather do it mathematically than with lots of data conversion.

View 3 RepliesConvert A Double X To A Decimal Y?
Oct 5, 2011Let'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)
