I hold a bachelor's in math. In my current job, I use basic algebra and trigonometry on a regular basis, and occassionally basic calculus. I have never had to use the theoretical information or complex analysis directly, but the practice gained in studying the theory and the proofs has helped me indirectly many times in programming. For most people. in depth knowledge of mathematics is of limited use, but in depth knowledge of problem solving gained by studying math can be invaluable. As you mentioned, it varies wildly by your career path of course.
