所以我编写了一个mips代码来查找圆柱体的表面区域。我会在这里分享一些......
.text
main:
#Get height
li $v0, 4 #Load syscall print
la $a0, height
syscall #print
#Store height
li $v0, 6 #read float
syscall #make the call
move $t0, $v0 #make height $t0
#Get radius
li $v0, 4 #Load syscall print
la $a0, input2
syscall #print
#Store radius
li $v0, 6 #read float
syscall #make the call
move $t1, $v0 #make radius $t1
li.s $t3, 3.14159265359
li.s $t5, 2.0
#Calculate the surface area
add.s $t4, $t0, $t1
mul.s $s0,$t4, $t1
mul.s $s1, $s0, $t3
mul.s $s2, $t5, $s1
我知道就寄存器而言，浮点数没有正确写入。我需要了解如何将其调整为浮点数的精确度。谢谢
此外，如果您对数学感到好奇SA = 2 * pi 半径（半径+高度）
编辑：尝试将所有内容转换为浮动寄存器的新尝试

main:
#Get height
li $v0, 4 #Load syscall print
la $a0, height
syscall #print
#Store height
li $v0, 6 #read float
syscall #make the call
mov.s $f0, $v0 #make height $f0
#Get radius
li $v0, 4 #Load syscall print
la $a0, input2
syscall #print
#Store radius
li $v0, 6 #read float
syscall #make the call
mov.s $f1, $v0 #make radius $f1
li.s $f8, 3.14159265359
li.s $f7, 2.0
#Calculate the surface area
add.s $f2, $f0, $f1
mul.s $f3,$f2, $f1
mul.s $f4, $f3, $f8
mul.s $f6, $f7, $f4
我从这里得到的错误是mov.s $ f0，$ v0
中的语法错误答案 0 :(得分：2)
以下是一个让您入门的示例：
.data
height: .asciiz "Enter height: "
input2: .asciiz "Enter radius: "
pi: .float 3.14159265359
two: .float 2.0
.text
main:
#Get height
li $v0, 4 #Load syscall print
la $a0, height
syscall #print
#Store height
li $v0, 6 #read float
syscall #make the call (input value stored on $f0)
mov.s $f1, $f0
#Get radius
li $v0, 4 #Load syscall print
la $a0, input2
syscall #print
#Store radius
li $v0, 6 #read float
syscall #make the call
mov.s $f2, $f0
l.s $f3, pi
l.s $f5, two
#Calculate the surface area
add.s $f4, $f2, $f1
mul.s $f0, $f3, $f5
mul.s $f0, $f0, $f2
mul.s $f12, $f0, $f4
li $v0, 2 #print float (input expected in $f12)
syscall #make the call
请注意，您必须使用带有add.s / mul.s指令的浮点寄存器。另请注意，syscall 4返回浮点寄存器f0
