# 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..

## 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.

## Estimating Ï€ To >14 Decimal Places?

Oct 30, 2010

My computing teacher challenged me to write a console program in Visual Basic.NET which would calculate Ï€, AKA Pi, to 14 decimal places. I contemplated various algorithms, then settled for a variant of Leibniz's series which would converge rapidly whilst being simple to implement.After about 30 minutes or so of programming I had finished my program which could generate the first 14 decimal places of Ï€ in a mere 27 iterations, below is the source code:

[Code]...

However, to my dismay, I soon discovered that this was all my program was capable of because of the IEEE specifications for numbers, although I've heard of people generating Ï€ to thousands of decimal places using unmodified Personal Computers so if you could tell me how I should modify my code to work around this to generate say 500 more decimal places.

## Formatting Decimal Places?

Feb 27, 2011

I have designed a unit converter that converts between different units. The value and unit to be converted from are entered in the first text box, for example "1 km" and the unit to be converted to is entered in the second text box. Then after pressing the calculate button, the new value will be displayed in the second text box as the output. By default the output will be specified to two decimal places. However, if the input has any number of decimal places, for example "1.045 km" the output should be displayed to the same decimal place, in this case 3.Displaying the output to two decimal places was easy enough to figure out, I just used:

FormatNumber(finalValue, 2)
But I'm completely stuck on the other part however and I'm wondering if anyone here has any suggestions. I thought about doing something like this:

## Formatting Numbers With Decimal Places?

Jan 12, 2012

I'm a noob, so please bear with me. I'm working with VB in Visual Studio 2008. I have an application that displays dollar amounts. With the application installed on my desktop all of the dollar values display with 2 decimal places. However, after moving the application to the server and executing from there, trailing zeroes after the decimal point are lost.

For example - 7.00 displays as 7 - 10.60 displays as 10.6 I'm guessing there's an options file somewhere that determines how these numbers are displaying but I have no idea what that file might be.

Can someone tell me how to get both digits following the decimal point to display all of the time?
