How to write a small number using java

Question

How to write a very small number, which is approaching the limit 0? Like this:

double eps = 0.000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000001;

This is a constant, but in the code it looks terrible. Is there a shorter form?

Java supports scientific notation for expressing double literals. You can write a small number, say, 10^-12 like this:

double eps = 1E-12;

It would be worth adding that Java has a minimum number it can store in ``. – Nic Nov 15 '15 at 01:34
