给定数值 meaning in Chinese

prescribed value

The floor ( ) function returns the value of a number rounded downwards to the nearest integer
函数的作用是：通过舍去法取整（即：返回的值必须是小于等于给定数值的最大整数）。
In this thesis , we present a fast self - adaptive algorithm for fredholm integral equations of the second kind with weakly singular kernels . briefly speaking , we design an algorithm which can determine the correlated parameters such that the corresponding numerical solution has given accuracy
本文考虑核函数有弱奇性的第二类fredholm积分方程的自适应快速数值解法，即事先给定数值解的精度，设计算法确定相关的参数使得数值解满足精度要求。
