Given a real number between 0 and 1 (e.g., 0.72) that is passed in as a double, print the binary representation. If the number cannot be represented accurately in binary with at most 32 characters, print "ERROR."

float？
float x=0.72;
char * p= (char*)&x;
for(int i=0; i< 4;i++)
  for(int j=7;j>=0;j--)
       cout<<((*p+i)>>j&1);

从0开始每次增加(0.5)^n如果得到的数不大于输入值,直到得到的数等于输入值或者n=30。

原来看错题了。。。那循环加就好了。。。

* method:
* 我擦，大二时候学的数电知识竟然用到了。。。。给跪了。。。
* 有时间把任意数的转换方法写出来。。。。

multitply by 2 and divide by 1
then use the reminder to do again...

Should the binary presentation follow the IEEE floating point representation rule?
Like one bit sign bit, 8 bits for exponent and 23 bits for fraction?
