Am trying to make a sum of an array which has double. However I am getting wrong answer.
var d1 = new double[] { 26392.23, 35192.23, -26392.23, -35192.23 };
var d2 = d1.Sum(x => x);
output: 7.27595761418343E-12
Expected Output: 0

Because of `double` representation in memory – Pavel Anikhouski Jan 31 '20 at 10:56

1This is just how floating point arithmetic works. Not every number can be represented with unlimited precision, so there are small errors when performing floating point maths. – haldo Jan 31 '20 at 10:57

1`var d2 = d1.Sum(x => (decimal)x);`? – SᴇM Jan 31 '20 at 10:58

1`var d2 = d1.Sum(x => (float)x);` should work too – Innat3 Jan 31 '20 at 11:06

@SᴇM it returns 0.00. Still expected is 0 – Amit Kumar Jan 31 '20 at 11:16
