// CATCH_CONFIG_WINDOWS_SEH : is Windows SEH supported?
// CATCH_CONFIG_POSIX_SIGNALS : are POSIX signals supported?
// CATCH_CONFIG_DISABLE_EXCEPTIONS : Are exceptions enabled?

* Implementation of uniform distribution on floating point numbers.

* implementation. Also note that we don't implement all parts of

* can the range be arbitrarily reset.
*
* The implementation also uses different approach than the one taken by
* `std::uniform_real_distribution`, where instead of generating a number
* between [0, 1) and then multiplying the range bounds with it, we first
* split the [a, b] range into a set of equidistributed floating point
* numbers, and then use uniform int distribution to pick which one to
* return.
*
* This has the advantage of guaranteeing uniformity (the multiplication
* method loses uniformity due to rounding when multiplying floats), except
* for small non-uniformity at one side of the interval, where we have
* to deal with the fact that not every interval is splittable into
* equidistributed floats.
