Compare double to zero using epsilon
...grammer is intending. Assuming 64-bit IEEE 754, in your example same(0, 1e-100) returns false, which is probably not what the programmer wants. The programmer probably rather wants some small threshold to test for equality, e.g. +/-1e-6 or +/-1e-9, instead of +/-nextafter.

How do I get whole and fractional parts from double in JSP/Java?
...ting double to int is almost always a bad idea. Because e.g. for (long)1.0e100 you will get 0. A lot of the times you need the double value simply "floored" for which there is floor(). If you want both integral and fraction parts use modf(). Really, this is a bad answer.
