title: Convert Decimal number into Fraction
body: <p>I am trying to convert decimal number into its fraction. Decimal numbers will be having a maximum 4 digits after the decimal place.
  example:- 12.34 = 1234/100
  12.3456 = 123456/10000</p>
  
  <p>my code :-</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  int main(void) {
    double a=12.34;
    int c=10000;
    double b=(a-floor(a))*c;
    int d=(int)floor(a)*c+(int)b; 
    while(1) {
       if(d%10==0) {
      d=d/10;
      c=c/10;
   }
   else break;
    }
    printf("%d/%d",d,c);
   return 0;
  }
  </code></pre>
  
  <p>but I am not getting correct output, Decimal numbers will be of double precision only.Please guide me what I should do.</p>
