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.

(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

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.

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.

Multiply by 1....
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.

See this link
Why don't you use format function with format strings ? Example:
sb.panels[2].Text := Format('%8.2f',[123.456]);
Other functions would be
function FormatFloat(const Format: string; Value: Extended): string; overload; function FormatFloat... .

So, I have a decimalfield that can be 3 different values. In my view, I pass in a dictionary of values that contains the appropriate decimal values as keys.

Simplest solution is to define a method on the model which encapsulates the numeric logic and returns the human-friendly string .
I'd make my own template tag if I were you .
According to this , it seems you can only compare strings .

I'd like to group the digits in a double by thousands, but also output however number of decimals are actually in the number. I cannot figure out the format string.
1000 => 1,000 1 => 100,000 123.456 => 123.456 1 .21 => 100,000.21 100200.1...

However, since you can only store a very limited precision, you can just use that and add the commas for thousands et al, but I don't know if it will keep the decimals, otherwise.
Of decimals.
