Problem 226. What are the odds?
Two numbers, A and B are drawn randomly and uniformly on [-R,R]. What is the probability that A*B < A+B. Your function should take one variable, R, and return the probability to within 100*eps. For example, if R = 1/2, then the probability should be:
0.560930216216329

Please update the last test case:
"Error: BITMAX has been removed. Use FLINTMAX instead."
Good problem, but the required precision is way too high. It not only prohibits brute-force methods but also multiple integrations. I was forced to find the corresponding isocurve, which was a little annoying (in other words, the formula which rendered the greatest precision).
