* Make explicit that we expect co-ordinates to be finiteEdward Welbourne2021-02-041-11/+7
| | | | | | | | | | | | | | | | | | | The various spatial-vector, line, point, region and margin types have all long taken for granted that their co-ordinates are finite and, in particular, not NaN. Make this expectation explicit in the documentation. Added assertions where (chiefly) noexcept and (where the assertion would be a simple qIsFinite() call) constexpr didn't preclude doing so. Also assert against zero divisors that would lead to non-finite results. Make minor clean-ups to docs in the process. QMarginsF had several methods whose declaration, definition and docs weren't consistent in their parameter names.

* Add qHypot() to qmath.h, exposing and extending std::hypot()Edward Welbourne2021-01-271-7/+5
| | | | | | | | | | | | | | | | | | | | We have plenty of places where we add some squares and take a square root; this may be done more accurately and faster by hypot(). Introduce QHypotHelper to handle hypot with more than 3 parameters, and with 3 when the C++17 version is missing (which it never should be). Include an overload taking arbitrarily many valus and ensure that we can use qHypot() with qfloat16. Illustrate with some example uses, add some tests. [ChangeLog][QtCore][QMath] Header <QMath> now provides qHypot(), an implementation of std::hypot() taking arbitrarily many numeric values, including support for qfloat16, while avoiding the overflow and underflow problems that arise when naively taking the square root of a sum of squares.

* Change QLineF::setLength() to work whenever length() is non-zeroEdward Welbourne2021-01-051-5/+6
| | | | | | | | | | | | | | | | Previously it only worked when isNull() was false, which is true for very short lines, even though length() may be non-zero. [ChangeLog][QtCore][QLineF] QLineF::setLength() will now set the length if the line's length() is non-zero. Previously, it was documented to only set the length if isNull() was false; this is a fuzzy check, so isNull() could be true for a line with non-zero length().

* Deal with {und,ov}erflow issues in QLine's length handlingEdward Welbourne2020-09-301-15/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use std::hypot() instead of sqrt() of a sum of squares. This ensures length() can't be zero when isNull() is false. Use length() in QLine::setLength() rather than duplicating that. Clarify and expand some documentation; isNull() never said what constituted validity, nor did unitVector() mention that is should not be used on a line for which isNull() is true. Make clear that lines of denormal length cannot be rescaled accurately. Given that we use fuzzy comparison to determine equality of end-points, isNull() can be false for a line with displacements less than sqrt(numeric_limits<qreal>::denorm_min()) between the coordinates of its end-points (as long as these are not much bigger); squaring these would give zero, hence a zero length, where using hypot() avoids the underflow and gives a non-zero length. Having a zero length for a line with isNull() false would lead to problems in setLength(), which uses an isNull() pre-test, protecting a call to unitVector(). (It was already possible for a null line to have non-zero length; this now arises in more cases.) Restored QLine::setLength() to the form it had before a recent change to avoid division by zero (which resulted from underflow in computing the length of a non-null line) but allow for the possibility that the unit vector it computes as transient may not have length exactly one. Add tests against {ov,und}erflow problems in QLine. Reworked the test added during the divide-by-zero fix to make it part of the existing test.
