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```
