since riscv divide by zero will not cause exception.

should I cause one by myself??

Why has RISC-V output -1 or xFFFFFFFF from dividing by 0?

As i know, the result of dividing by 0 in RISC-V ist -1(signed), 0xFFFFFFFF(hex). But i dont know the reason why the RISC-V outputs this code. Also How is this procedure justified? Thank you!
