VS 2008 - Working With Doubles - Numbers Seem To Round After The Decimal Point
Apr 1, 2009
intLoginTime = txtLoginTime.Text
intLogoutTime = txtLogoutTime.Text
[CODE]..........
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'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]

What would be the code to validate a textbox so that it can only accept positive numbers and a decimal point? If no value is entered, it automatically enters 0.

I'm trying to get my decimals to display with four decimal places. The DB rounds my number to 4 decimal places, but it returns the number with trailing 0s (due to the decimal precision of the field), so something like 9.45670000.[code]...
How do I format my decimal, so that the number of decimal places is always four?

I'm using ROUND() to calculate the value in one column from values in the others and it displays to a lot of decimal place.Its rounded correctly to 1 decimal place but when shown the the datagridview it displays like 12.3000000000..All 3 values used to calculate this one are stored to two decimal place, not that that should matter.[code]

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.

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

I'm trying to do this division and the result to be displayed on a eight decimal number.
Dim r1 As Integer
Dim r2 As Double
r1 = Val(TextBox16.Text)
r2 = r1 / 60
TextBox18.Text = FormatNumber(r2, 8)
The value or R1 on this case is 273.4 but it varies according with the result obtained so I can not allocate a constant number to r1. The problem is the result that I am getting is 4,55000000 instead of 4.5566666

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"?
