<h1>数学函数 - fmod</h1>
<p>原型extern float fmod(float x, float y);</p>
<p>用法:#include &lt;math.h></p>
<p>功能计算x/y的余数</p>
<p>说明返回x-n*y符号同y。n=[x/y](向离开零的方向取整)</p>
举例:<pre>
// fmod.c
#include &lt;syslib.h>
#include &lt;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;
}
