#include <stdio.h>
int main(void)
{
float fbuff,ftmp;
int i;
for (i = 5;i <= 8;i++){
ftmp = 0;
switch(i){
case 5:
ftmp = 10 * i;
break;
case 6:
ftmp = 1 * i;
break;
case 7:
ftmp = 0.1 * i;
break;
case 8:
ftmp = 0.01 * i;
break;
}
if (i == 0){
fbuff = 0;
}
fbuff = fbuff + ftmp;
printf("ftmp = %f\n",ftmp);
printf("fbuff = %f ftmp = %f\n",fbuff,ftmp);
}
return 0;
}
実行結果が下記になる理由を教えて下さい。どうして「0.000003」多くなるのでしょうか？
fbuff = 56.780003 ftmp = 0.080000
