我一直在做这个任务，但不能通过第一部分，这应该很简单。我已经和我的教授讨论过了，但他也想不通……我希望在这里能得到一些帮助。我只想输入一个数字，将其推入st0，然后将其弹出并存储到total_mean中。出于测试目的，我在开头注释掉了代码。
extern printf
extern scanf
segment .data
prompt_name db "Please enter you name: ", 0
input_name db "%s %s",0
ready db "Please have your numberic data ready",10,0
get_num db "Enter a floating number: ",0
stringdata db "%s",0
namedata db "%s ",0
display_name db "%s",10,0
floatdata db "%Lf",0
ask db "Are there more numbers (Y or N)? ", 0
mean db "The mean of these %d values is %Lf",10,0
largest db "the largest value is %Lf",10,0
smallest db "the smallest value is %Lf",10,0
more db "Do you have more data to analyze (Y or N)? ",0
bye db "Thank you %s. I hope you enjoyed this program.",10,0

它只是我试图从我遇到问题的键盘输入的下半部分。当我输入一个数字（例如 12.0）并显示它时，它显示 0.00000。任何人都可以帮我找到解决方案吗？
