The problem is that the numbers seem to round after the decimal point, so if I entered a login-time of 8.15 and log-out 9.30, instead of showing 1.15 as the difference, it shows '1'. is there a way around this?
I've made a lot of progress on my project. Only question I have now is how do I limit a textbox to only allow users to input numbers and one decimal point? The point of the decimal point is to make it currency. So if the answer of my calculation is 56.56566 I only want it to be $56.57.
View 5 RepliesHow 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 get the second decimal point?

How can I display this with 2 decimal places?
I have an id called "AM01". I separated them by truncating the numbers out and increase it by 1 each time I want to add a new record. Therefore before I add the record, I would have to combine them back. I managed to truncate them and combine them back. However, the results turn out to be "AM2" instead of "AM02". So, is there a way where I could make the numbers as "02" instead of just "2"?

View 2 RepliesI 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.
I was wondering how i can get as far as the second point in a Double.

View 6 RepliesFor 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)

I am making a Rubik's Cube timer, and I converted the times to milliseconds so I can calculate the average of 5 with that.

View 2 RepliesI 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

I create a calculator in visual basic and I put button from 0 to 9 ... and event click textbox1.text = textbox1 + "1" (to 9) ..it work good .. but if i press key 0 from keybord nothing is hapens ..
and the secoun problem .. if I put for example 3.25.89 not 3.2589 how can write in code a "if" for example if textbox1.text -alredy contain a point (.) 3.25 then I click again on button point .. it remain 3.25 but not 3.25.
I'm drawing polygons,lines,etc. and I have to have the points of each precise - up to 12 decimals. Since a Point only takes integer values, I'm not sure how to handle scaling. I have a working user control, but rounding the decimals so I can put them into points is causing incorrect calculations (area, ect.).
