# FloorMod

#### 场景说明

给出输入张量input，取模张量mod以及长度length，计算两个输入张量的逐元素模运算，将计算结果存储于输出张量output。例如：

```
input: [5,7,15,7]
mod: [8,6,20,3]
output: [5,1,15,1]
length: 4
```


#### 代码示例

```
#include <cmath>
#include <random>
#include <cstdint>
#include <iostream>

#include "ktfop.h"
int main()
{
    using namespace ktfop;
    size_t length = 4;
    float inputArray[] = {5, 7, 15, 7};                               
    float modArray[] = {8, 6, 20, 3};                                 
    float *input = inputArray;                                   
    float *mod = modArray;                                        
    auto *output = new float[4];                                   
    int ret = -1;
    //调用FloorMod算子，结果存储于output数组。第一个参数及第二个参数均为数组
    ret = FloorMod(input, mod, output, length);
    std::cout << "output: [";
    for (int i = 0; i < 4; ++i) {
        std::cout << output[i];
        if (i < 3) {
            std::cout << ", ";
        }
    }
    std::cout << "]" << std::endl;         
    //传入空指针，打印日志"ERROR Parameter verification failed for the FloorMod Op."
    ret = FloorMod(static_cast<float *>(nullptr), mod, output, length); 
    //传入空指针，打印日志"ERROR Parameter verification failed for the FloorMod Op."
    ret = FloorMod(input, mod, static_cast<float *>(nullptr), length);  

    //情况一：调用FloorMod算子，结果存储于output数组。第一个参数为数组，第二个参数为一个元素
    ret = FloorMod(input, mod[0], output, length);              
    //传入空指针，打印日志"ERROR Parameter verification failed for the FloorMod Op."
    ret = FloorMod(static_cast<float *>(nullptr), mod[0], output, length); 

    //情况二：调用FloorMod算子，结果存储于output数组。第一个参数为一个元素，第二个参数为数组
    ret = FloorMod(input[0], mod, output, length);              
    //传入空指针，打印日志"ERROR Parameter verification failed for the FloorMod Op."
    ret = FloorMod(input[0], static_cast<float *>(nullptr), output, length); 
    delete[] output;
}
