[19] in set theory, the epsilon numbers are ordinal numbers that satisfy the fixed point ε = ω ε The first epsilon number, ε 0, is the limit ordinal of the set {ω, ω ω, ω ωω, } in numerical analysis and statistics it is used as the error term in group theory it is used as the idempotent group when e is in use as a variable name

微积分定理中，特别是关于函数极限定理，就是根据这种ε-δ语言来证明的。换句话说，没有使用ε-δ语言的微积分缺乏严格的定义 [2]。然而另一方面，除了数学之外，在 自然科学 、 工程学 、 经济学 、 医学 、 社会学 的 领域，有观点认为没有必要使用ε-δ语言，有没有必要教ε-δ语言是数学教育
