VB 2010 - Unwanted Rounding To Nearest Integer (Whole Number)
Apr 28, 2011
I have a program that will round any numbers I give it regardless of the data type I set (I've tried double and decimal) before it saves into the DB. I'm using MS access for the DB and I've set the data types in access to Numeric Double, Numeric Decimal, and Currency and all with decimal places set to 4 -- all to no avail.
What I do know:
1) The textboxes on the form accept the number value as I enter it and after I hit save the value displayed is the same as the number that I entered. However, once I query the database again for that entry the value has been rounded up/down to the nearest integer (whole number). For example: I enter 1000.50 and hit save. I search for that same entry and the value is saved as 1000. If I enter 1000.51 and hit save then search for the entry it shows the value saved as 1001.
2) I can store the desired value directly into the DB by manually entering it. When I search for that entry from within the program it displays the correct amount. HOWEVER, if I try to change the amount and then hit save I get a concurrency violation.
I think that it may be a setting somewhere in the program that doesn't allow for decimal places but I've search everywhere and I cant find anything.

I'm trying to round a double to the nearest 5th or 10th number. So far my code looks like this basically:
'Mathamatical equation For Cost to Mow
dbCost = (txtArea.Text / dubMetres) + intExclusions * 3 + (intIrregular / 2)
Dim dbRounded As Double
'Trying to round to nearest 5 or 10

I'm doing an assignment for class which is basically a simple program that takes 12 monthly temperatures and averages them. But I also need to round the average to the nearest tenth. I am not particularly good at programming or math and don't know how I would fit this into my code. I am Including My program thus far. I put in bold and italic where the calculation takes place.
Private Sub btnEmterTemperature_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEmterTemperature.Click

How would I go about rounding up decimal numbers to the nearest 2 decimal places? For example $7.0000032 would be $7.01 In theory, VB would make it $7.00 but if it is > $7.00, I want it to reflect that to the nearest penny... so $3.0000001 would be $3.01

i'm building an image library and one of the things i want to do is compare the most common color in a given image to a set of established colors in rgb format the way i'll probably do this is create 3 arrays for the average r,g and b of each given image, and then compare them to my established values for r,g and b that i want to match to so if my first image has the average values of 255, 125 and 5 for r,g and b..what would be the best way to do a nearest match against my pre-established colors? (about 32 in total)

I'm quite a newbie in VB.NET (and VB on the whole). So my question could sound rather odd, but still. I've stumbled upon an issue with the CInt and converting a double to an integer.
The issue is the following: CInt(10.5) would be 10
CInt(10.51) would be 11, but I expected 10... (Got used to C# style conversion: (int)10.51 would be 10)
As pointed out here Integer.Parse VS. CInt the result is just rounded in some fashion. Nowever, all I need is to get only integer part and throw away the fractional one. How can I achieve such type of conversion in VB.NET? After a short research I assume that I can use Fix() funciton to do the trick, but is it the best choice ever?

For example, how would I get the # "220" from the number "229". Or the number "300" from "309"? The only way I've found to do this is using string stuff, but I'm afraid of the overhead for strings?

I'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]

I want this to return 0 to me, integer 0 (no decimals), but vb.net rounds this to 1.
Can someone hint me up how to accomplish this ?

I am working in excel trying to setup a function involving multiplying a cell by a set number and then having the result round to the nearest 10. Here's the beginning of my function statement fx=e3*1.026. say the result is 8654, I need it to round to 8650. Also if it comes back 8655, I need it to round to 8660. I have about 2,000 records I need to do this to so I was hoping that one formula or statement could be used for all my data.

I have read several solutions for doing rounding up a number. What I am trying to accomplish is is a number which is calculated in in one text box called txt6 which has 10 decimal places, I am trying to use that number for a roundup with no decimal places.
Calculation for txt6:
If CheckBox1.Checked = False Then
txt6.Text = Val(lbl7.Text) * Val(txt1.Text) * 0.0032808399 + 0.0833333333 'array length panels in portrait mode
txt7.Text = Val(lbl5.Text) * Val(txt1.Text) * 0.0032808399 + 0.0833333333 'array length panels in portrait mode
End If

I am building a tool that takes an XML document and replaces XML nodes with a different XML node using .ReplaceChild. This all works great. The nodes get changed to the proper nodes. Where I seem to be having an issue is that the new node is inserted with an xmlns="" attribute, which I am not specifying for it to do, nor do I want as an attribute. How can I stop the ReplaceChild from inserting this as an attribute, or am I going to have to remove the attribute after the node is replaced?
Dim imgSrcNode As XmlElement = xmlDoc.CreateElement("img")
Dim imgSrcAttr As XmlAttribute = xmlDoc.CreateAttribute("src")
imgSrcAttr.InnerText = "./art/" + imageName.Substring(0, imageName.LastIndexOf("."))
imgSrcNode.Attributes.Append(imgSrcAttr)
mmlNode.ParentNode.ReplaceChild(imgSrcNode, mmlNode)
Resulting XML change:
<img src="./art/equJI161298_1" xmlns="" />
XML change desired:
<img src="./art/equJI161298_1" />
