Hi,
I am using an ASP.NET GridView control with a TemplateColumn which has a TextBox in the ItemTemplate . I am binding the Text of the TextBox with the values from database. The database holds these values with five decimal points, and for the interface...

You could always validate that the data has indeed changed at all in that column before updating it .

I am writing a function to extract decimals from a number. Ignore the exception and its syntax, I am working on 2.5.2 (default Leopard version). My function does not yet handle 0's. My issue is, the function produces random errors with certain numbers...

As Ned Batchelder said, not all decimals are exactly representable.
The problem is that (binary) floating point numbers aren't precisely representable as decimals.

When 2 decimal(30,10) numbers are divided in Sql Server 05, 2 last decimals seem to be getting lost (not even rounded off, simply truncated).
For example:
Declare @x decimal(30,10) Declare @y decimal(30,10) Declare @z decimal(30,10) select @x = 2.1277...

Hi Guys, I have a textbox for 'Area '.I need a regularexpression to validate textbox such that it should allow decimals to enter but no characters.Anyone can help me

(dot without decimal)
You have lots.
'^[0-9]*$'
If you want decimals, this should work:
/^(?:\d+\.?)|(?:\d*\.\d+)$/
What is the format with one or two decimals, but would not work with 34.

Using the following code snippet:
(fromIntegral 100)/10.00
Using the Haskell '98 standard prelude, how do I represent the result with two decimals?
Thanks.

You can use printf :: PrintfType r => String -> r from Text.Printf :
Prelude> import Text.Printf Prelude Text.Printf> printf "%.2f\n" (100 :: Float) 100.00 Prelude Text.Printf> printf "%.2f\n" $ fromIntegral 100 / 10.00 10.00
%f formats... .

I've always been curious: how can I perform arithmetic operations on very long decimals--for example, calculating pi to the 3000th decimal place (especially in an imperative language)?

For keeping track of how many decimals to shift over by to get a sort of arbitrary precision floating point.

decimals in this thread .
And (for financial applications) fixed point decimals, or map them to language-specified or user-defined types representation for date/time, but you can also localize to whatever time zone is pertinent.

Lets say that input from the user is a decimal number, ex. 5. 2155 (having 4 decimal digits). It can be stored freely (int,double) etc.
Is there any clever (or very simple) way to find out how many decimals the number has? (kinda like the question how...

A double is stored in a binary form, so no obvious ... .
E.g:
.2155 * 10 = 2.155 .155 * 10 = 1.55 .55 * 10 = 5.5 .5 * 10 = 5.0
4 steps = 4 you mean "stored freely (int"? Once stored in an int, it has zero decimals left, clearly.
Of decimals.

I'm using decimal type (.net), and I want to see if two numbers are equal. But I only want to be accurate to 10 decimal places. For example take these three numbers. I want them all to be equal.

Thanks.
What about multiplying by 10^10 and dropping the fractional part?
decimal x2 = Math.Truncate(x * 1 ); decimal y2 = Math.Truncate(y * 1 ); Assert.Equals(x2, y2);
EDIT: Changed to Math.Truncate by Aaron's suggestion.

Using the function "double F (int i)" wrote on that topic will give you the value of PI after "i" terms .
