Hi,
2) Wrappers around integral floating-point types to support wider exponent range. Another problem that I faced is conversion from bigint to double. The maximum double exponent is 1023, which is quite small to handle intermediate values of the geometric predicates. I ended up with implementing floating point type wrapper that extends double exponent to int64 range and think it is quite useful feature for problems that operate with big integers.
I like that idea. We have also been implementing our own floating point numbers with a base of 10, because of requirements in the financial business. I think it should be feasible to write a general wrapper for floating point numbers with an arbitrary base as well. Taking all that together we could have e.g. floating point numbers to a base of 77 with five byte mantissa and 42 bytes exponent, if needed anywhere.
