There are 3 failing tests in assert.m which arise from the fact that Windows systems display scientific notation with 3 digits in the exponent. Although this seems not to follow the C++/C standard (https://groups.google.com/forum/?_escaped_fragment_=topic/comp.lang.c%2B%2B.moderated/GL7lutrLNoU#!topic/comp.lang.c%2B%2B.moderated/GL7lutrLNoU) it's what were stuck with. The failing tests can be worked around by looking for a slightly different regular _expression_ to indicate success. However, when compiling with MSVC there appears to be a way to switch the compiler to using 2-digit format (http://stackoverflow.com/questions/9226400/portable-printing-of-exponent-of-a-double-to-c-iostreams).
#ifdef _MSC_VER // Set scientific format to print two places. _set_output_format(_TWO_DIGIT_EXPONENT); #endif
It might be useful to try and put that code snippet in Octave, but I don't compile with MSVC and without a way to verify things I'm sure I would screw it up.
