mips - Print out rounded floating point number in MIPS

Question

I am not sure how to print out a floating point single with one decimal place.

I get '88.09999847' instead of '88.1'. Please advise

For example: if I have register $f10 = '88.09999847'

mov.s   $f12,   $f10

li  $v0,    2   

syscall

I get output as "88.09999847"

How do I round up to one decimal place and print out "88.1"

Any help would be appreciated

1）将数字乘以 10（因为您要四舍五入到小数点后一位。）
2）将数字压入堆栈（或适当的寄存器。）
3）回合是系统调用（在我的机器上，代码是call roundf）
4 ) 将结果除以 10
