the limitation of upload_max_filesize, post_max_size

Hi, I know that we can limit the size of upload file by specify upload_max_filesize, post_max_size and even memory_limit parameters. Though we can change these parameters, can someone please let me know what the maximum value of these parameters can be? What is the factors we need to take into account when specify these values.
