Disregard A Decimal Point?

Sep 24, 2009

I am trying to move some data from an Excell sheet to an AS/400 file.

I have my app working, in that, the data is getting to the correct table, but the problem I'm having is that one of the columns in the spreadsheet contains numbers ie; 1234.55

I need to get that to the AS/400 as 123455 in a text field.

Currently I am moving the data from one dataset to another as follows.

Dest_DS.Tables(0).Rows(i).Item(0) = Data_DS.Tables(0).Rows(i).Item(0)

I think what I need to do is seperate the whole number from the decimal and then concatenate the values. ?Not sure how to.

Also, some of the values in the spreadsheet may end in a zero such as 1234.50 but only show the 1234.5 so even fnding the decimal and then taking the next two characters won't always be correct.

How To Get Comma Instead Of Decimal Point In Label

Aug 11, 2009

For some time I try to get the comma instead of the decimal point, but the labels I use won't display a comma. For some reason I don't understand, the msgbox() does the trick, but is useless in my application. This is my last desperate piece of code I tried but it also failed.

Expresserprijs = EuropluscolNL(ArrayCol, 2) - EuropluscolNL(ArrayCol, 1)
' All above are "Doubles" and are fed with data like 21,45 (with comma's that is)
Decimaalteken = Expresserprijs
' Decimaalteken is a string
MsgBox(Decimaalteken)

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?

Round Decimal Point Up To Nearest Whole Number?

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]

Floating Point - Displaying A Decimal With A Given Maximum Length?

Apr 28, 2010

I am writing a custom totaling method for a grid view. I am totaling fairly large numbers so I'd like to use a decimal to get the total. The problem is I need to control the maximum length of the total number. To solve this problem I started using float but it doesn't seem to support large enough numbers, I get this in the totals column(1.551538E+07). So is there some formating string I can use in .ToString() to guarentee that I never get more then X characters in the total field? Keep in mind I'm totaling integers and decimals.
