I need to roundup the number to 2 decimals in xslt.
1.231>>1.24
1.238>>1.24
Do we have any function defined?
Do we have any function defined?
The ceiling() function rounds up to the nearest integer, so do:
ceiling($n * 100) div 100

I'm new to VB.net coding i would like to know how to round of a decimal number to the nearest integer
Eg. X= (5-2/2) = 1.5
but I need only as 1.
Thank you.
You can use the integer division operator if you just want to discard any remainder:
Dim resultValue As Integer = (5-2) \ 2
Note that this is one of the differences between VB.NET and C#, in C# the normal division operator will always apply integer division, so discard the remainder.
You have other options:
resultValue = CInt(Math.Floor((5-2) / 2))
resultValue = CInt(Math.Round((5-2) / 2, MidpointRounding.ToZero))
Try this:
Math.Round( (5-2)/2, 0)
..and look into the options for the overload with the MidpointRounding param, which you can set to influence rounding when the result ends with .5. Here are some of the available options:
Math.Round((5 - 2) / 2, MidpointRounding.AwayFromZero)
Math.Round((5 - 2) / 2, MidpointRounding.ToEven)
Check the documentation (or trial & error) to see which best suits your needs.
Or if you always want either the integer below or the integer above, then also check out Math.Floor and Math.Ceiling functions.
I think you can use the floor function. For example, double floor(double x);, the floor function returns the largest integer that is smaller than or equal to x.
I wanna round "2.765467..." number to "2.70".
How can i do that?
İ tried Math.round or math.floor but not working:(
Anyone can send a code for vb.net?
It sounds like what you want to do is truncate, not round. Try this:
Dim decTemp = (10 ^ NumberOfPlaces)
Return CDec(Fix(ToTruncate * decTemp) / decTemp)
Where ToTruncate is the number you'd like to truncate, and NumberOfPlaces is the number of decimal places you want to truncate to. In your case:
Dim ToTruncate As Decimal = 2.765467D
Dim NumberofPlaces as Integer = 1
Dim decTemp = (10 ^ NumberOfPlaces)
Return CDec(Fix(ToTruncate * decTemp) / decTemp)
I've read much about rounding in Excel. I found out that VBA's Round() function uses "Bankers rounding" while Application.WorksheetFunction.Round() uses more or less "normal" rounding. But it didn't help me to understand this:
? Round(6.03499,2)
6.03
Why? I want to see 6.04, not 6.03! The trick is that
? Round(Round(6.03499,3),2)
6.04
I thought a bit and developed a subroutine like this:
Option Explicit
Function DoRound(ByVal value As Double, Optional ByVal numdigits As Integer = 0) As Double
Dim i As Integer
Dim res As Double
res = value
For i = 10 To numdigits Step -1
res = Application.Round(res, i)
Next i
DoRound = res
End Function
It works fine.
? DoRound(6.03499,2)
6.04
But it is not cool. Is there any built-in normal rounding in Excel?
If you round 6.03499 to 3 digits it will be 6.035 - which is correct.
If you round 6.03499 to 2 digits it will be 6.03 - which is correct
However - the example where you first round to 3 digits, then to 2 is also correct, by the following statement:
Round(6.03499, 3) gives 6.035
Round(6.035, 2) gives 6.04
If you want Round(6.03499, 2) to give 6.04 you have to use Application.WorksheetFunction.RoundUp
Rounding 6.0349 to two decimals is just not 6.04 hence, no, there is no such function.
Round up will round anything up. Hence, 6.0000000001 will also become 7 if you round to 0 decimals.
I have code like this:
Dim minutes As Integer = (55 / 60)
I want this to return 0 to me, integer 0 (no decimals), but VB.NET rounds this to 1.
How do I accomplish this?
OK for those with the same problem, try dividing with \ (yeah, it's not escape character in VB.NET).
For full decimal division you have to use another operator.
Try:
\
Dim minutes As Integer = Math.Round(55 / 60)
There are overloads that allow rounding to fractional values and specifying which way to round if the value is exactly between two integers.
So round down? Use:
?Math.Truncate(55/60)
0.0
What is the syntax to round up a decimal leaving two digits after the decimal point?
Example: 2.566666 -> 2.57
If you want regular rounding, you can just use the Math.Round method. If you specifially want to round upwards, you use the Math.Ceiling method:
Dim d As Decimal = 2.566666
Dim r As Decimal = Math.Ceiling(d * 100D) / 100D
Here is how I do it:
Private Function RoundUp(value As Double, decimals As Integer) As Double
Return Math.Ceiling(value * (10 ^ decimals)) / (10 ^ decimals)
End Function
Math.Round is what you're looking for. If you're new to rounding in .NET - you should also look up the difference between AwayFromZero and ToEven rounding. The default of ToEven can sometime take people by surprise.
dim result = Math.Round(2.56666666, 2)
You can use System.Math, specifically Math.Round(), like this:
Math.Round(2.566666, 2)
Math.Round(), as suggested by others, is probably what you want. But the text of your question specifically asked how to "roundup"[sic]. If you always need to round up, regarless of actual value (ie: 2.561111 would still go to 2.57), you can do this:
Math.Ceiling(d * 100)/100D
The basic function for rounding up is Math.Ceiling(d), but the asker specifically wanted to round up after the second decimal place. This would be Math.Ceiling(d * 100) / 100. For example, it may multiply 46.5671 by 100 to get 4656.71, then rounds up to get 4657, then divides by 100 to shift the decimal back 2 places to get 46.57.
I used this way:
Math.Round(d + 0.49D, 2)
Math.Ceiling((14.512555) * 100) / 100
Dot net will give you 14.52. So, you can use above syntax to round the number up for 2 decimal numbers.
I do not understand why people are recommending the incorrect code below:
Dim r As Decimal = Math.Ceiling(d * 100D) / 100D
The correct code to round up should look like this:
Dim r As Double = Math.Ceiling(d)
Math.Ceiling works with data type Double (not Decimal).
The * 100D / 100D is incorrect will break your results for larger numbers.
