But if Trio isn't used, then some other generic floating point library is
needed.
As I've found out testing XPath expressions, the native support for floats
provided by the compilers is highly variable especially with (but not
limited to)
+ / - Infinity and NaN. A library like Trio is required to provide
consistancy
across different compilers and platforms

Can Trio not be fixed to improve it's accuracy rather than removing it
altogether?
