检测浮点数是否过大（溢出）

Question

我从MIPS开始，已经分配了一个作业，我必须在其中找到三角形的斜边（所有这些都是单精度浮点数）。但是，在每一步中我都要检查是否有溢出，将数字与IEEE754表示进行比较＆＃34;无限＆＃34;，但我不知道如何做到这一点，我将不胜感激任何帮助。

编辑：到目前为止，我只有输入的代码。

.text
main:
in1:    li $v0,4            #
        la $a0,inleg1       #message to request leg 1
        syscall             #
        li $v0,6            #read entered value as float
        syscall
        mov.s $f1,$f0       #move read value --> $f1=leg1

    #So now I have to include a condition to detect overflow, and show an error message and request the number again
    #The idea is to compare $f1 with infinity, and if it's not smaller, we have overflow
    #Then I have to repeat the evaluation after every operation performed
