People usually just live with the inaccuracy of floating point and it works fine if you know what you are doing. error accumulation. In the above example, you are actually rounding off the starting float 4 times, each time it becomes more and more inaccurate! It could easily arise as the result of a calculation that would have result 1. 0 in infinitely precise real number arithmetic. For those numbers, the largest gap is about 1e- 16 and the worst case rounding error is about 5e- 17. Here is a program that.

For example, consider the function f( x) = a * ( b - ( c+ d) ) No big deal, or is it? It turns out it is when d. For example, a fixed- point representation that.
