/* cppunit-1.13.2 uses assertion_traits<double>
* sprintf( , "%.*g", precision, x)
* to format a double. The actual comparison is performed on a string.
* This is problematic with mingw/windows|wine, "%.*g" formatting fails.
*
* This quick hack compares float, however float compatisons are at most Y.MMMM+eXX,
* the max precision needs to be limited. to the last mantissa digit.
*
* Anyway, actual maths is verified with Linux and OSX unit-tests,
* and this needs to go to https://sourceforge.net/p/cppunit/bugs/
