X bottles of beers, take y down, x and y are in Real Numbers Set

x bottles of beers, take y down, x and y are in Real Numbers Set is a program designed and implemented by PSTF.

This is the ADVANCED version of 99 bottles of beer. It receives two real number as input and assign them to x and y, and then print these lyrics(x and y has precision of 3 decimal digit, end if x≤0):

x bottles of beer on the wall,
x bottles of beer.
Take y down and pass it around, 
x-y bottles of beer on the wall.

x-y bottles of beer on the wall,
x-y bottles of beer.
Take y down and pass it around, 
x-(2×y) bottles of beer on the wall.

将 i 初始化为 x 。
清空屏幕。
重复执行以下代码直至 i 不大于 0 ：
{
    输出“%1 bottles of beers on the wall, \n%1 bottles of beers.\n”。%1将被 i 替代。
    将 i 减去 y 。
    输出“Take %1 down and pass it around,\n %2 bottles of beers on the wall.\n\n”。%1将被 y 替代，%2将被 i 替代。
}
输出“No more bottles of beers on the wall, \nNo more bottles of beers. \n”。
输出“Go to the store and buy some more, \n%1 bottles of beers on the wall.”。%1将被 x 替代。
