Can someone debug this?

Question

C programming
It should output the denomination of the money. It worked for whole numbers, but for numbers with decimal places, it doesn't.
#include<stdio.h>
void main()
{
int rs = 0, a = 0, b = 0, c = 0, d = 0, e = 0, f = 0, g = 0, h = 0;
float i = 0, j = 0, k = 0, l = 0;

printf("Enter Amount : ");
scanf("%d", &rs);

while(rs >= 1000)
{
a = a + 1;
rs = rs - 1000;
}

while(rs >= 500)
{
b++;
rs = rs - 500;
}

while(rs >= 200)
{
c++;
rs = rs - 200;
}

while(rs >= 100)
{
d++;
rs = rs - 100;
}

while(rs >= 50)
{
e++;
rs = rs - 50;
}

while(rs >= 10)
{
f++;
rs = rs - 10;
}

while(rs >= 5)
{
g++;
rs = rs

Example input
2000
Output
1000: 2
500: 0
200: 0
100: 0
50: 0
20: 0
10: 0
5: 0
25 cents: 0
10 cents: 0
5 cents: 0
But if I inputed 2000.25
It doesn't read it

Answer 1

#include<stdio.h>
void main()
{
int rs = 0, a = 0, b = 0, c = 0, d = 0, e = 0, f = 0, g = 0, h = 0;
float i = 0, j = 0, k = 0, l = 0;

printf("Enter Amount : ");
scanf("%d", &rs);

while(rs >= 1000)
{
a = a + 1;
rs = rs - 1000;
}

while(rs >= 500)
{
b++;
rs = rs - 500;
}

while(rs >= 200)
{
c++;
rs = rs - 200;
}

while(rs >= 100)
{
d++;
rs = rs - 100;
}

while(rs >= 50)
{
e++;
rs = rs - 50;
}

while(rs >= 10)
{
f++;
rs = rs - 10;
}

while(rs >= 5)
{
g++;
rs = rs - 5;
}

while(rs >= 1)
{
h++;
rs = rs - 1;
}

while(rs >= 0.25)
{
i++;
rs = rs - 0.25);
}

while(rs >= 0.10)
{
j++;
rs = rs - 0.10;
}

Answer 2

while(rs >= 0.05)
{
k++;
rs = rs - 0.05;
}

while(rs >= 0.01)
{
l++;
rs = rs - 0.01;
}

printf("\n 1000 : %d", a) ;
printf("\n 500 : %d", b) ;
printf("\n 200: %d", c) ;
printf("\n 100 : %d", d) ;
printf("\n 50 : %d", e) ;
printf("\n 10 : %d", f) ;
printf("\n 5 : %d", g) ;
printf("\n 1 : %d", h) ;
printf("\n 25 cents : %f", i);
printf("\n 10 cents : %f", j);
printf("\n 5 cents : %f", k);
printf("\n 1 cents : %f", l);
return 0 ;
}
