取整函数及其生成的数列
Integer Rounding Functions and Related Sequences
【摘要】 讨论三类整数列,这些数列的后项均是由前项与非整数乘积再取整后得到的,对应的取整函数分别为四舍五入取整函数、下取整函数、上取整函数.结果表明这三类整数列均为二阶线性递归数列.
【Abstract】 For a given function,a sequence can be constructed as following:the current term is the function of the product of the previous term and a fixed non-integer constant.Three rounding integer functions are considered in this paper.The results indicate that the corresponding sequences are the second order linear recursion sequences.
