.SH "Detailed Description"
.PP 
Sort-key helpers used by \fBDiagram::toXml()\fP to serialize elements and conductors in a deterministic order\&. Pulled into their own header (instead of an anonymous namespace in \fBdiagram\&.cpp\fP) so they can be unit-tested directly -- see tests/qttest/tst_diagramsortkeys\&.cpp\&.

.SS "QString DiagramSortKeys::coordinateKey (double v)\fR [inline]\fP"
Format a coordinate as a string that sorts the same way the number does\&. Plain fixed-precision formatting ("%\&.4f") does NOT do this -- e\&.g\&. "15\&.0000" sorts before "5\&.0000" as text even though 15 > 5 -- so shift into a non-negative range and zero-pad to a fixed width before comparing\&.
