Help With Change Amount Program

My program is producing '0's' for the amount of each denomination of dollars/coins. 100 dollars, 50 dollars, 20 dollars, 10 dollars, 5 dollars, 2 dollars, 1 dollars, 50 cents, 20 cents etc...

Say if the user inputs: "102.80", It should produce output saying:
100dollars: 1
2dollars: 1
50 cents: 1
20 cents: 1
10 cents 1

Can anyone point out why it is producing 0's instead? Any help would be appreciated, thanks.

Code:

#include <stdio.h>

int GetChange()
{
	float change;

	printf("Please enter a change amount: ");
	scanf("%d%*c", &change);

	return (change);
}

int NumCents(int cents, int denomination)
{
	return (cents / denomination);
}

int RemainderCents(int cents, int denomination)
{
	return (cents % denomination);
}

int NumDollars(int dollar, int denomination)
{
	return (dollar / denomination);
}

int RemainderDollars(int dollar, int denomination)
{
	return (dollar % denomination);
}

void PrintChange(int n100dollars, int n50dollars, int n20dollars, int n10dollars, int n5dollars, int n2dollars, int n1dollars, int n50cents, int n20cents, int n10cents, int n5cents)
{
	printf("100dollars: %d\n50dollars: %d\n20dollars: %d\n10dollars: %d\n5dollars: %d\n2dollars: %d\n1dollars: %d\n50cents: %d\n20cents: %d\n10cents: %d\n5cents: %d\n", n100dollars, n50dollars, n20dollars, n10dollars, n5dollars, n2dollars, n1dollars, n50cents, n20cents, n10cents, n5cents);

	return;
}

int main()
{
	float change;
	int dollar, n100dollars, n50dollars, n20dollars, n10dollars, n5dollars, n2dollars, n1dollars;
	int cents, n50cents, n20cents, n10cents, n5cents;

	change = GetChange();
	dollar = (int) change;
	cents = (int) (((change - dollar)*100) + 0.5);
	
	n100dollars = NumDollars(dollar, 100);
	dollar = RemainderDollars(dollar, 100);
	
	n50dollars = NumDollars(dollar, 50);
	dollar = RemainderDollars(dollar, 50);
	
	n20dollars = NumDollars(dollar, 20);
	dollar = RemainderDollars(dollar, 20);
	
	n10dollars = NumDollars(dollar, 10);
	dollar = RemainderDollars(dollar, 10);
	
	n5dollars = NumDollars(dollar, 5);
	dollar = RemainderDollars(dollar, 5);
	
	n2dollars = NumDollars(dollar, 2);
	dollar = RemainderDollars(dollar, 2);
	
	n1dollars = NumDollars(dollar, 1);

	n50cents = NumCents(cents, 50);
	cents = RemainderCents(cents, 50);

	n20cents = NumCents(cents, 20);
	cents = RemainderCents(cents, 20);

	n10cents = NumCents(cents, 10);
	cents = RemainderCents(cents, 10);

	n5cents = NumCents(cents, 5);

	PrintChange(n100dollars, n50dollars, n20dollars, n10dollars, n5dollars, n2dollars, n1dollars, n50cents, n20cents, n10cents, n5cents);

	return(0);
}

 

Nevermind, i've solved it.

In the GetChange function i was scanning in a 'decimal' when it's meant to be a 'float', "%f%*c".

Haha, oh dear.
