numbers

问题 As the title suggests I would like to convert a long number to the format with words using C#. The Culture settings don't seem to do this and I am just currently doing this String.Format(new CultureInfo("en-IN"), "{0:C0}", Price) But for very long numbers I would prefer the word format. I am not from India and only vaguely familiar with how the system works. 回答1: While I can't give you the code itself, here's the system 1 - One 10 - Ten 1000 - Thousand 10000 - Ten Thousand 100000 - Lakh

问题 How can I create a random number when I define a global declaration in an Uppaal program? I want to have a variable that contains a random number as in a C program: int x = rand (100); 回答1: According to folks at Uppaal mailing list , this code snippet select: i : int[0,3] will non-deterministically bind i to an integer in the range 0 to 3. So, in Your case just use select: x : int[0, 100] . 回答2: I think the proper answer is: it is not possible when defining the global declaration. The syntax

问题 I don't think it is hard, just tedious to write: Some small free (as in beer) library where I can put in a String like 1,2-9,33- and it can tell me whether a given number matches that expression. Just like most programs have in their print range dialogs. Special functions for matching odd or even numbers only, or matching every number that is 2 mod 5 (or something like that) would be nice, but not needed. The only operation I have to perform on this list is whether the range contains a given

问题 I have a need to create a graph, where the scale of the Y-axis changes depending on the data input into the system. Conceivably this scale could be anywhere from 0-10, 0-100, or even have bottom limit of thousands and an upper limit of millions. To properly determinethe scale of this axis, I need to work out the ratio of Points to Pixels (based on graph height/range). Now a graphs' axis never start at the lowest value and go to the highest, usual practice is to go to the next nearest 2, 5 or

问题 I would like a clear explanation of Num , Real , Integral , Integer , Int , Ratio , Rational , Double , Float . 回答1: This answer mostly assumes you know the difference between types and type classes. If that difference is hazy to you then clear up your understanding there before reading on. Num Num is a typeclass that includes all numeric types. :info Num class Num a where (+) :: a -> a -> a (-) :: a -> a -> a (*) :: a -> a -> a negate :: a -> a abs :: a -> a signum :: a -> a fromInteger ::

问题 I have three text fields all which are numbers or a decimal number. They are accepted as strings which are later converted. However, i want to validate these fields so that only the numbers or decimal numbers are accepted. Whats the easiest way to ensure that these fields are only characters 0-9. I would prefer an if statement but any solution would be nice! 回答1: Use string.matches method which accepts a regex as an argument. if(string.matches("\\d+(?:\\.\\d+)?")) { System.out.println(

问题 Is it possible to localize numbers in String.format call the same way as NumberFormat.format does? I've expected it simply to use String.format(locale, "%d", number) but this doesn't return the same result as if using NumberFormat. For example: String.format(Locale.GERMAN, "%d", 1234567890) gives: "1234567890", while NumberFormat.getNumberInstance(Locale.GERMAN).format(1234567890) gives: "1.234.567.890" If it can't be done, what's recommended way for localizing text including numbers? 回答1:

问题 What's the shortest regex that can match non-zero floating point numbers with any number of decimal places? It should accept numbers like -1 -5.9652 -7.00002 -0.8 -0.0500 -0.58000 0.01 0.000005 0.9900 5 7.5 7.005 but reject constructions such as . .02 -. -.996 0 -0 0. -0. -0.000 0.00 -- .. + +0 +1 +. +1.26 ,etc I do not need support for the scientific notation, with e , E and such. The language I'm using is C#, by the way. 回答1: ^-?(0\.\d*[1-9]|[1-9]\d*(\.\d+)?)$ EDIT Updated to reflect new
