float and UINT转换问题
新手问题～怎么转回1072048784来？
程序代码：
#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
int main(int argc, char* argv[])
{
unsigned int B=1072048784;//3F E6 2A 90
printf("%u\n",B);
float Result1=0;
memcpy(&Result1, &B, sizeof(float));
printf("%f\n",Result1);
printf("//----------------------------\n");
char A[]={"1.798174"};
printf("%s\n",A);
int Result2=0;
memcpy(&Result2, &A, strlen(A));
printf("%u\n",Result2);
printf("//----------------------------\n");
float C=(float)atof(A);
printf("%d\n",C);//若注解这行则下一行出的数值又会变～这是为何？
printf("%u\n",C);
return 0;
}
1072048784
1.798174
//----------------------------
1.798174
959917617
//----------------------------
939524096
1073741824 or 939524096 //若注解上一行则出的数值会变
