如何在装配中进行浮点乘法？ [英] how can do float multiplication in assembly?

问题描述

我想写这段代码：

I want to write this code:

y= 0.4*x+1 

但是我有一些错误MIPS组装





我在寄存器$ t1中有一个整数值，我想将它乘以0.4但它在第二行有错误：

but I have some errors in MIPS assembly


I have an integer value in register $t1 and I want to multiply it with 0.4 but it has error in the second line:

li.s $f0, 0.4
mul.d $f1, $f0, $t1
mfhi $a2
mflo $v0

# print the result
li $v0, 2 # load appropriate system call code into reg $v0
la $a0, 0($v0) # load address of string to be printed on $a0
syscal

推荐答案

t1我希望将它倍增0.4但是哈哈第二行中的错误：

t1 and I want to multiply it with 0.4 but it has error in the second line:

li.s

f0， 0 。 4
mul.d

f0, 0.4 mul.d

f1，
