choose(n,k) = choose(n,n-k) is not satisfied if either

1. n is a negative integer with k a positive integer (due to automatically
returning 0 for n-k<0)

2. n is not an integer with k a positive integer (due to rounding n-k to an
integer, compounded by automatically returning 0 if n<0 which implies n-k<0)

Both are easily fixed, as discussed in PR# 10766
