How much math?

Hello, /prog/. I'm currently going to school for computer science, and I was curious as to how math-intensive real-world programming is. Can you get by just being comfortable with arithmetic and algebra? Or do you need to be able to do Calculus and Trigonometry like a professional to actually be able to be good and employable?

In the real business world, a Math PHD or even a professor on the bill will let you know what you should do as a programmer, programming really hard math stuff... Just to let you know, I've written countless of mathematical algorithms that makes 0 sense to me. That's the life of a programmer son!
