more = (1 == scan.nextInt());
}


}
}


it does not calculate properly when I input the amount 68.97
please help
thank you!

my program needs to be able to read the amount of money and then output how many tens, fives, ones, quarters, dimes and so on that are needed to make the amount.
When I run the program it does everything right except it does not calculate the amount of pennies right:
----jGRASP exec: java PP_2_11a

Enter amount of money.
68.97
6 ten dollar bills
1 five dollar bills
3 one dollar bills
3 quarters
2 dimes
0 nickels
1 pennies
Enter 1 to continue, 0 to quit >

there should be 2 pennies but I do not understand why it is not calculating it right.

Add some printlns in your code to print out the intermediate values so you can see what is happening.

I was able to find out where it went wrong when I put in the printlns-thank you!
