Hello, I just wonder about one thing: I saw that a company stopped spending a single penny in maintenance for what it was selling, so obviously it was selling less than before but they were still selling a bit, thus the "money gained"/"money invested" ratio was not just like 1000/0.00001 which would be already a big number, but basically 1000/0, and while dividing by 0 isn't possible, the story I'm telling basically still mean that the ratio should sort of be equal to "more than infinite" since when I say that they didn't spend a single penny, I really mean that it's not 1000/0+ but really 1000/0, so I just wonder, is there a name or symbol for this situation that replace the words "more than infinite" ?
