In my project I have to compute division, multiplication, subtraction, addition on a matrix of `double` elements.
The problem is that when the size of matrix increases the accuracy of my output is drastically getting affected.
Currently I am using `double` for each element which I believe uses `8 bytes` of memory & has accuracy of `16 digits` irrespective of decimal position.
Even for large size of matrix the memory occupied by all the elements is in the range of few kilobytes. So I can afford to use `datatypes` which require more memory.
So I wanted to know which data type is more precise than `double`.
I tried searching in some books & I could find `long double`.
But I dont know what is its precision.
And what if I want more precision than that?
