How do I round money to the nearest cent in C programming?

Question

I'm writing a program in C (NOT C ++) to convert money and I need to round U.S. currency to the nearest cent. How do I round money to the nearest cent?

Ex: $0.501 rounds to $0.50,
$0.505 rounds to $0.51,
$1.006 rounds to $1.01,
etc.

I'm a begginer at programming, so please give me simple solutions that are easy to understand, as I do not know much about C programming.

Answer 1

read each number as a char array.
compare last digit with five
if greater than five add 1 to previous character.

then print array n-1 element

Answer 2

As far as I remember, C does not support a Currency data type and so you will have to use Float / Double variables to do this. You can use "round()" method by including file.
