Webb채택된 답변: Kaustubha Govind. I'm trying to understand what kind of protection I can get against division by zero, both at the model level and in the C/C++ code. One option I've thought about has been to create my own divisor block, where I can control the divisor/denominator away from 0 if it ever is zero. Is this the only way, or am I ...
