## [Solved] Why does floating-point arithmetic not give exact results when adding decimal fractions?

Binary floating point math is like this. In most programming languages, it is based on the IEEE 754 standard. The crux of the problem is that numbers are represented in this format as a whole number times a power of two; rational numbers (such as 0.1, which is 1/10) whose denominator is not a power … Read more

## [Solved] C# – Math.Sqrt() returning decimals

Casting to integer (Int32) drops the fractional part of your number… int number = (Int32) 3.14159; // value of number will be 3 (not 3.14159) // Do this instead double c = Math.Sqrt(c2); // will give you the result you want output.Text = Convert.ToString(c); solved C# – Math.Sqrt() returning decimals

## [Solved] Why does >= operator work as > operator in C when compared with 0.9 [duplicate]

Your code is equivalent to: double x1 = 0.9; float xf = (float)x1; // discard some precision double x2 = (double)xf; if (x2 >= x1) { // … } The problem is that, after you discarded some precision from x1 by converting it to float, it can never be recovered; casting it back to double … Read more

## [Solved] Named int vs named float

The comment in the link says “integer, pointer and member pointer template parameters arenâ€™t lvalues” (emphasis mine). It does not say that named integer variables are not lvalues – they are. If there were such a thing as floating-point template parameters, then they wouldn’t be lvalues either; but named floating-point variables still would be. solved … Read more

## [Solved] How to add decimal to floating point number with non-decimal value [closed]

Nothing to stop this float fun(float a) { cout << fixed << setprecision(1); return a; } But that’s stupid code for a stupid puzzle. What does this have to do with real programming? 3 solved How to add decimal to floating point number with non-decimal value [closed]

## [Solved] can’t multiply matrix and list which type ‘float’

You are multiplying a list by a float. You should multiply each row of the matrix with words. Something like this will work. multiply_nonspam_test = [] for row in transpose_test_feature: multiply_nonspam_test.append([x*y for x,y in zip(row, log_train_probs_nonspam_words)]) print multiply_nonspam_test 0 solved can’t multiply matrix and list which type ‘float’

## [Solved] Print command output [closed]

If you consult the documentation for printf in C and System.out.println in Java, you will see that they format output in different ways. This is because they are totally different, and I’m not sure why you expected them to produce the same results. If you want printf-style formatting in Java, consider using String.format() to format … Read more
