<pre>
原型：extern float fmod(float x, float y);
用法：#include <math.h>
功能：計(jì)算x/y的余數(shù)
說(shuō)明：返回x-n*y，符號(hào)同y。n=[x/y](向離開(kāi)零的方向取整)
舉例：
// fmod.c
#include <syslib.h>
#include <math.h>
main()
{
float x,y;
clrscr(); // clear screen
textmode(0x00); // 6 lines per LCD screen
x=74.12;
y=6.4;
printf("74.12/6.4: %f\n",fmod(x,y));
x=74.12;
y=-6.4;
printf("74.12/(-6.4): %f\n",fmod(x,y));
getchar();
return 0;
}
