如何提取数字的小数部分并将其输出到控制台？

Question

我对汇编语言相当陌生，并且对如何截断浮点数然后使用该整数来运行程序感到困惑。我目前能够很好地运行该程序，但是，我无法让程序截断输入的浮点数并将其转换为整数。这是我到目前为止所拥有的。

    .data
Prompt: .asciiz "\n Please Input a value for N = "
Result: .asciiz "\nThe sum of the integers from 1 to N is "
FP_Run: .asciiz "\nYou have entered a floating point number. The number you entered will be truncated. "
Bye:    .asciiz "\n **** Adios Amigo - Have a good day****"
