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
