I am using Objective-C to retrieve some information about the hard drive. I successfully retrieve the amount used in bytes.
However I am having trouble converting bytes to gigabytes. When doing this programatically, I get 76,768,641,024 bytes. I then convert this to GB: 76,768,641,024 bytes/(1024* 1024 * 1024) = 71.5 GB. My Mac reports the exact same amount of bytes. However it reports that this is equal to 76.77 GB!
Why is there a difference in GB if the amount of bytes is the same?
I am on a iMac running OSX Snowleopard.
