My program is showing compiler error

Pooja would like to withdraw X $US from an ATM. The cash machine will only accept the transaction if X is a multiple of 5, and Pooja’s account balance has enough cash to perform the withdrawal transaction (including bank charges). For each successful withdrawal the bank charges 0.50 $US.

Calculate Pooja’s account balance after an attempted transaction.

Input

Positive integer 0 < X <= 2000 - the amount of cash which Pooja wishes to withdraw.

Nonnegative number 0<= Y <= 2000 with two digits of precision - Pooja’s initial account balance.

Output

Output the account balance after the attempted transaction, given as a number with two digits of precision. If there is not enough money in the account to complete the transaction, output the current bank balance.

Example - Successful Transaction

Input:

30 120.00

Output:

89.50

Example - Incorrect Withdrawal Amount (not multiple of 5)

Input:

42 120.00

Output:

120.00

Example - Insufficient Funds

Input:

300 120.00

Output:

120.00

Here’s my code

# #include

using namespace std;

int main()

```
{
float x,y;
cin>>x>>y;
if(x%5==0&&y>x+0.5)
{
cout<<(y-x)-0.5;
}
else
cout<<y;
return 0;
}
```

Here’s the error

prog.cpp: In function ‘int main()’:

prog.cpp:7:6: error: invalid operands of types ‘float’ and ‘int’ to binary ‘operator%’

if(x%5==0&&y>x+0.5)

```
^
```

Can somebody help me
