# interval
Loosely speaking, an interval is a part of the real numbers that start at one number and stops at another number. For instance, all numbers greater that $1$ and smaller than $2$ form in interval. Another interval is formed by numbers greater or equal to $1$ and smaller than $2$. Thus, when talking about int... |
