**Q: I've noticed that Jep.Net does not give accurate results for certain expressions.
Why is this? What can I do about it?**

A:You will notice that when you evaluate something as simple as "8 - 7.9" the result will be 0.09999999999999964 rather than 0.1. These inaccuracies are the result offloating point arithmetic. Internally, Jep.Net uses the`double`

type to represent numbers by default. Unfortunately, even for trivial calculations such as "8 - 7.9" the calculation can not be performed accurately.You will notice the same if you run the following code.

double a=8, b=7.9; System.out.println("a-b = " + (a-b)); //prints: a-b = 0.09999999999999964So this is not a Jep.Net flaw, just a limitation of using floating point numbers. Although floating point numbers are accurate enough for many applications, these types of errors should not be ignored in applications where accuracy is critical.
