How to allow two numbers after decimal points ?
View 1 RepliesI am working on a program where specific strings are being read from a file and displayed in a listview. Some of the strings represent money values though the file has no decimal points. I would like to add a decimal point before the last 2 digits of prices, quantities, and freights when displayed in the listview (not add two decimal places but actually insert the decimal point into the string). I would like to be able to keep most of the code I already have though, and I have no clue how to accomplish this. Here is the code I am using to fill the listview:

How can I change the IF statement to accept the ascii code of decimal points? Then... how can I make sure the user doesn't enter 354.5.3535.5.0 as a number? Is there some sort of built in library in VB that has a pattern matching for US currency or do I have to write it myself?

I need the application version as an integer with decimal points eg: 1.2 At the moment I'm using:

I'm trying to alter the existing number formatting in my company's application to make it more readable for international users. This is a stock trading application, so most stock prices come in with numbers precise to 2 decimal points, like so-> 17.23 We could also get ticks in that have precision out to 4 decimal points, so a penny stock might be 0.0341. The original string format that we were using for stocks was "#,##0.00##" Which would give us the format we wanted (essentially trimming '0's). The problem here is the ',' and '.' are forced onto the user, where in many other countries the thousands separator is '.' and the decimal point is ','. Boss man doesn't want to use "N4" for all numbers, even though this would resolve the globalization issue. Is it possible to have a globalized custom string format?
Other options besides writing some middle man code to internationalize numbers formatted the original way or another string.format method?

View 2 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

Is it casting from a double to a decimal implicitly. How would I do this explicitly in vb.net?
1) One Decimal Varibale stores a decimal value
2) The value must be converted in string ( some time the comma is used as decimalplaceholder some time the dot)
3) the user modifies the value
4) i need to riconvert the string back in decimal
how can i do this
so:

I have a project where I want to have checked arithmetic by default, except for one performance sensitive spot. Unfortunately, VB.Net doesn't have an 'unchecked' block.Ideally the framework would have some sort of integer type with explicitly unchecked arithmetic, but I didn't find anything like that. I did find that expression trees have binary expressions for unchecked operations, but the delegate overhead cancels out the unchecked advantage (and then some).
Currently I'm converting the inputs to UInt64/Int64 before doing the arithmetic, then converting back (with a bitwise And to ensure in-range). It's about 50% slower than unchecked arithmetic (according to profiling).
Moving the arithmetic-sensitive part to a project with unchecked arithmetic might work, but it seems like overkill to give it an assembly all to itself.
