decimal

I see that, in C#, rounding a decimal , by default, uses MidpointRounding.ToEven . This is expected, and is what the C# spec dictates. However, given the following: A decimal dVal A format string sFmt that, when passed in to dVal.ToString(sFmt) , will result in a string containing a rounded version of dVal ...it is apparent that decimal.ToString(string) returns a value rounded using MidpointRounding.AwayFromZero . This would appear to be a direct contradiction of the C# spec. My question is this: is there a good reason this is the case? Or is this just an inconsistency in the language? Below,

I want to validate that a number has certain parameters, for example I want to ensure that a number has 3 decimals is positive. I have searched in different places over the internet, although I could not find how to do it. I have made that text box to accept numbers only. I just need the rest of the features. Thanks, $("#formEntDetalle").validate({ rules: { tbCantidad: { required: true, number: true }, tbPrecioUnidad: { required: true, number: true }, } messages: { tbCantidad: { required: "Es Necesario Entrar una cantidad a la orden" }, tbPrecioUnidad: { required: "Es Necesario Entrar el valor

When I tried to convert something like 0.1 (from user in textbox), My value b is always false. bool b = Decimal.TryParse("0.1", out value); How can it be here to work? Too late to the party, but I was going to suggest forcing the culuture to en-US but Invariant is a better sln decimal value; bool b = Decimal.TryParse("0.1", NumberStyles.Any, new CultureInfo("en-US"), out value); Specify the culture for the parsing. Your current culture uses some different number format, probably 0,1 . This will successfully parse the string: bool b = Decimal.TryParse("0.1", NumberStyles.Any, CultureInfo

I found out that there is function called .hex.to.dec in the fBasics package. When I do .hex.to.dec(a) , it works. I have a data frame with a column samp_column consisting of such values: a373, 115c6, a373, 115c6, 176b3 When I do .hex.to.dec(samp_column) , I get this error: "Error in nchar(b) : 'nchar()' requires a character vector" When I do .hex.to.dec(as.character(samp_column)) , I get this error: "Error in rep(base.out, 1 + ceiling(log(max(number), base = base.out))) : invalid 'times' argument" What would be the best way of doing this?

I am having to interface some C# code with SQL Server and I want to have exactly as much precision when storing a value in the database as I do with my C# code. I use one of .NET's decimal type for a value. What datatype/precision would I use for this value in SQL Server? I am aware that the SQL Server decimal type is the type that most likely fits my needs for this. My question though is what scale and precision do I use so that it matches .NET's decimal type? You can use the SQL Server decimal type ( documentation here ). That allows you to specify a precision and scale for the numbers in

I am interested in how to round variables to two decimal places. In the example below, the bonus is usually a number with four decimal places. Is there any way to ensure the pay variable is always rounded to two decimal places? pay = 200 + bonus; Console.WriteLine(pay); Use Math.Round and specify the number of decimal places.
