Get The Nearest Number Divisible By 10?

Jul 6, 2009

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?

Check If A Number Is Evenly Divisible By Another?

Jan 20, 2012

I was wondering what the fastest way is to check for divisibility in VB.NET.I tried the following two functions, but I feel as if there are more efficient techniques.

Function isDivisible(x As Integer, d As Integer) As Boolean
Return Math.floor(x / d) = x / d
End Function

Another one I came up with:

Function isDivisible(x As Integer, d As Integer) As Boolean
Dim v = x / d
Dim w As Integer = v
Return v = w
End Function

Converting Some Php Code That Tries To Get A String To A Length That Is Divisible By A Certain Number?

Dec 10, 2009

I'm converting some php code that tries to get a string to a length that is divisible by a certain number, say 10. To do so it appends "�" to the string to make up for the difference. In other words, it does something like:

dim difference as integer = 10 - (str.Length Mod 10)
for i as integer = 1 to difference
str += "�"
next

But the problem for me is that "�", which is the ascii code for the null character, is two strings and I don't believe that when VB loops over resultant string it will view that as one character. what could I append the string with to retain the expected behavior?

Round Decimal Point Up To Nearest Whole Number?

May 14, 2011

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]

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.

Setup A Function Involving Multiplying A Cell By A Set Number And Then Having The Result Round To The Nearest 10?

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.

Determining If Numbers Are Evenly Divisible

May 30, 2012

In my order program, I need to determine if the quantity ordered is full boxes.For example - all of our parts/products have different box quantities, and when a customer orders a certain quantity, I want it to do nothing when I type in the quantity IF the order quantity is even boxes, If it is not even boxes, I want a pop up form with three radio buttons to come up. The three radio buttons will have the next higher even box quantity, the next lower box quantity, and to keep the current quantity and apply a broken box charge. I have this pop-up form done except for determining if the order quantity is an even number of boxes, and then determining the next higher and next lower.

Just to clarify - let's say a customer orders a part that has 60 pieces per box. If he orders 180 pieces, nothing happens and you can continue to put the order on. If he orders 200 pieces, a pop-up form with 3 selections - "keep current quantity and apply broken box charge", or "Change Quantity to 240", or "Change Quantity to 180" comes up.

Finding The Nearest Colour?

Jan 9, 2008

I have written a program to return the colour of a pixel from an image. The problem I have is I need to return the colour name. Of course not all colours returned will be one of the pre-defined colours (knowncolours), so my question is, is there a way to find the nearest knowncolour which matches the colour of the pixel?

I have looked at GetNearestColour but am confused by its function. It just seems to return the same colour as the parameter passed into it.

Round Off To The Nearest Highest .25?

Nov 15, 2011

getting a formula round off to the next highest .25.example:

2.35->2.50
2.26->2.50
2.24->2.25
2.51->2.75

I can't use the Round function because if I have 2.26 then it will round off to 2.25 which is unacceptable.I have been using the Ceiling function but it rounds it off to the nearest highest integer. Which can add an almost extra kg,lb to my formulas.

.net - MSChart Nearest Data Point?

Oct 27, 2011

I use Mschart to produce charts. What I am trying to get is the nearest data point by where I click on the chart. The problem is that I can't find any connection between the HitTest values and the data point x/y values.Say, I clicked on the following point:

Dim result As HitTestResult = Chart.HitTest(e.X, e.Y)I have now values of X and Y where I clicked. How to associate it with the data point values?

What I want to achieve is to double-click on the chart which would find the nearest data point (x,y as integer) and knowing these values I would be able to recalculate other values based upon where the user needs it and double-clicks.

Integer Nearest Match Comparison

Jan 25, 2009

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?

Two Decimal Point Rounded To Nearest 20

Aug 20, 2010

I have read about Round() and MidpointRounding.ToEven but I still could not figure how to use it to achieve what I want. I have numbers (usually from 5 digit decimal) such 125.36 , 125.10, 125.99. I want to make the 2 decimal point rounded to the nearest 20. Means, the 2 decimal point should be either .00 or .20 or 0.40 or .60 or 0.80 only.
125.36 should be 125.40 : 125.10 should be 125.00, 125.99 should be 126.00
125.54 should be 125.60 and so on
Is there math function to make or I should parse the number as text and test the last 2 digit?

Way To Force Calculations To Round Up Currency Values To Nearest Whole Pence / Cent

Jan 23, 2009

I'm trying to find a way to force my calculations to round up currency values to the nearest whole pence/cent.By default, rounding will round to the nearest pence/cent, whether this is up or down.I need it to always round up regardless.[code]My client's back office system rounds in this manner which is rather peculiar to say the least, however the prices on his website need to match and to to this they need to be rounded up.The built in ASP.NET Math.Round function only offers the regular rounding(and banker's rounding) and not an option to force rounding up or down.
