鸭嘴兽又名鸭獭,它是哺乳类的脊椎动物,却偏偏又是卵生,它不但有鸟类的喙,也会像鸟类一样自己营造窝巢孵蛋.它在水中游行像鱼一般自如,在陆地上又有爬虫类的两栖性能.取整函数兼顾了常函数与一般函数的特征,是常函数与一般函数的过渡,由于它的存在,函数王国更加丰富多彩.定义设x∈R,用[x]表示不超过x的最大整数,则y=[x]称为取整函数,也叫高斯函数,显然y=[x]的定义域为R,值域为Z,称[x]为x的整数部分,称x-[x]为 Platypus, also known as otter, is a mammalian vertebrate, but it happens to be oviparous, it not only has the beaks of birds, it will also create their own nest nest eggs like birds, it is like a fish in the water parade freely, Amphibious properties of terrestrial reptiles are also found on land. The rounding function takes into account the characteristics of both regular and general functions and is a transition between ordinary and general functions. Due to its existence, the function kingdom is more colorful and colorful. Definition Let x∈R, If [x] is the largest integer that does not exceed x, then y = [x] is called the rounding function, also called Gaussian function. Obviously, the domain of y = [x] is R and the range is Z. The integer part of x, said x- [x] is
