WebFor many applications such as numerical integration, differential equation approximation, plotting a 3d surface, optimization problems, Monte-Carlo simulations, etc., one wishes to pass around and evaluate a single algebraic expression many, many times at various floating point values. ... TypeError: unable to simplify to float approximation ... WebThe present patch simply remedies this by adding a few lines to bessel_ {I, J, K, Y} to check whether the input was real, and if so, to take the real part of the return value. This is definitely the easiest solution, but maybe a better one exists based on how Sage calls scipy. Attachments (3) Oldest first Newest first Threaded

In other words, 12 and 35 have no prime factors in common — and as a result, there isn’t much overlap in the irrational numbers that can be well approximated by fractions with 12 and 35 in the denominator.
