c# - Floating-point error when not assigned to a float variable -


I have a static method GetFraction which gives the st in the price below: 

  Public static class PriceUtil {public static intra fracturing (float price) {int price int = (int *) (100 * value); Return value value 100%; }}   
 $ 23.79 for the price, this method gives 78 cents instead of 79. While debugging, I have unknowingly set the bug as follows:  
  Public Fixed Class Price Unit {Public Fixed Ent Fret (Float Price) {Float Price = $ 100 value; Int priceInt = (price); Return value value 100%; }}   
 I do not understand that assigning (100 * value) in the float variable solves the problem. The FAIX, the whole number of casting is done on the same value as  int  bar  float   float .  
 Thanks for your reply in advance!  
  
 
 
 As written in the comments, you have a problem of  decimal  To avoid the  float  instead of type in the form.  
 Using the value  23.79f  does not describe the problem My computer is therefore my guess that the price has been calculated from the last few calculations. Here's a demonstration:  
  var value = 23.7899999f; Console.WriteLine (value); Var fraction = ((int * (value * 100))% 100; Console.WriteLine (fraction);   
 The output of this code is  
 23.79 78  
 Another possibility of the problem you experience is that  float  is a 32-bit floating point number and 80 bit floating point numbers are used internally on CPU counting. If you change the way you complete your calculations, you may find a slightly different depending on rounding or truncation. Results can be found. However, I suspect that this is an explanation of the results of your experience.  
 Before calculating the fraction, you should be able to solve your problem by rounding the value:  
  Var value = 23.789999 9F; Console.WriteLine (value); var round value = math Round (value, 2); Var fraction = ((int) 100 * round value)% 100; Console.WriteLine (fraction);   
 is now output  
 23.7979

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
