When Adding A Value To Another Value The Results Eventually Change From 2-decimal Places To Multiple Decimal Places?

Mar 13, 2009

Problem: Using the sub routing below, when adding a value to another value the results eventually change from 2-decimal places to multiple decimal places.Basically, the amount stored should always only be 2 decimal places, because the values passed in are always 2 decimal places. Output from calling the sub routine multiple times.

Running total = 329430.75
New Withheld Amount = 710.79
Running total = 330141.54

[code]....

As a workaround, I have a new routine that uses a custom round function to properly store only 2 decimal places - as the VB round function does not perform the type of rounding desired.I understand that we are removing the value from the dictionary and adding it back..

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]

User Set Number Of Decimal Places?

May 23, 2010

How do I enable a user to set the number of decimal places in my code?essentially I have multiple variables in my code ,different kinds of pressure for example and with each instance I declare the following;

txt_Alt_Press.Text = Strat_Press.ToString(Press_DP)

I then set Press_DP in a module, declared as a public variable,

Public Press_DP As String = ("F1")

So what I want to do is make the "F1" bit a variable in itself, so then the user can set the number of decimal places with a numeric up-down control.

RoundUp Function - Which Will Round A Number UP To The Specified Decimal Precision

Apr 29, 2009

I 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.

Display The Number With Two Decimal Places And Dollar Signs?

May 7, 2009

I need to write a program that uses constants to establish the base pay, the quota, and the commission rate. The Pay menu item calculates and displays the commission and the total pay for that person. However, if there is no commission, do not display the commission amount (do not display a zero-commission amount).Write a function procedure to calculate the commission. The function must compare sales to the quota. when the sales are equal to or greater than the quota, calculate the commission by multiplying sales by the commission rate. Format the dollar amounts to two decimal places; do not display a dollar sign.The summary menu item displays a message box that holds total sales,total commission,and total pay for all salesperson. Display the number with two decimal places and dollar signs. the Clear menu item clears the name, sales, and pay for the current employee and then resets the focus.The Color and Font menu items should change the color and font of the information displayed in the total pay text box.Use a message box to display the program name and your name as programmer for the about option on the Help menu.

[code]...

So the issue is when I push the pay/calculate button everything is calculating correctly the first time, but then when I push clear to input another workers name and weekly sales and push calculate, my label is blank and does not display any info about the second worker. Then when I push summary after inputting the second worker, it's only displaying the total calculations of the first worker. I can't seem to figure out this problem on my own (After countless hours staring at my code I might add!), so I am hoping somebody can pinpoint what I have done wrong? EVerything else is seeming to work just fine.[code]...

Rounding Up Decimal Numbers To The Nearest 2 Decimal Places?

Apr 17, 2010

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

How To Mix Decimal Places

Feb 22, 2012

Using Visual Studio I'm using TextRange processing a word at a time, parsing for figures and minus values etc. All of which works. However I have to honour the original number of decimal places in the figures, even though they may be 0's.ie -1219.0 and 1219.00 are both valid inputs the valid outputs would be(1,219.0) and 1,219.00, I can't just use tostring and stamp all of them as "N2" etc).I have to format including retaining the trailing 0 if necessary.I can use "#,##0.######" but that removes trailing 0's... ie both above example would be changed to 1,219 pos or neg.
