Write a C program that takes as input a positive fractional number and converts it to binary.

Code:

#include<stdio.h>
#include<stdlib.h>
main (void) //Program Start
{
	float Num; //Variables initialization. In this code "float" is used fot the
	float Denom; //fraction division and "int" is used for the other variables and
	int i; //parameters.
	int Number1;
	int n=0;
	int Numb[n];
	int j;
	int x=0;
	printf("Please enter the positive fraction numerator:\n");
	scanf("%f", &Num); //Asking for the numerator for the fraction division
	printf("Please enter the positive fraction denominator:\n");
	scanf("%f", &Denom); //Asking for the denominator for the fraction division
	Num = Num/Denom; //Numerator and denominatior division
	i = Num; //The division result is assigned to the "i" variable
	Number1 = i; //The value of "i" is assigned to the variable "Number1"
	Denom = Num-i; //The decimal side of the number is obtained
	do
	{
		Numb[n]= Number1%2; //Division remainder (residue)
		Number1 = Number1/2; //New value divided by 2
		n++; //The value of "n" is increasing during the "do-while" is running
	}
	while(Number1 != 0 ); //Comparing the number with "0"

	printf("\n");
	for(i=n-1; i>=0; i--) //Reversing the numbers order
	{
		printf("%d", Numb[i]);
	}
	printf("."); //Point between the integer and decimal part of the number
	Num = Denom; //Decimal value is asigneg to the "Demon" variable
	do
	{
		Num = Num*2; //Multiplpy by 2 for reached the 15 values
		j=Num; //Comparation
		if(j>0) //If the "j" value is greater a "1" is printed because a
	{	 //mutliplication by 2 give a result with a integer part and
	printf ("1"); //with a decimal part.
	Num = Num-j;
	}
	else //If the result of the multiplication dont give a integer
	printf ("0"); //part or a decimal part a "0" is printed.
	x++;

	}
		while(x!=15); //The maximun quantity of values for a binary number is 15
		printf("\n");
		system ("PAUSE"); //Pausing the result screen after the program run
	} //Program End
