[Tatsuro MATSUOKA]

Hello 

This mail reports the test of data.cc on octave-3.1.51 on mingw.

Integrated test scripts:

  C:\usr\tatsu\mingwhome\octaves\octave-3.1.51\src\data.cc  PASS  504/508  FAIL 
4

1. ***** assert(log2(complex(0,Inf)), Inf + log2(i));
!!!!! test failed
assert (log2 (complex (0, Inf)),Inf + log2 (i)) expected
Inf + 2.266i
but got
NaN - NaNi
NaNs don't match  

2.***** test
 [f, e] = log2 ([0,-1; 2,-4; Inf,-Inf]);
 assert (f, [0,-0.5; 0.5,-0.5; Inf,-Inf]);
 assert (e, [0,1;2,3;0,0])
!!!!! test failed
assert (f,[0, -0.5; 0.5, -0.5; Inf, -Inf]) expected
   0.00000  -0.50000

   0.50000  -0.50000
       NaN       NaN
NaNs don't match  

3.***** test
 [f, e] = log2 (complex (zeros (3, 2), [0,-1; 2,-4; Inf,-Inf]));
 assert (f, complex (zeros (3, 2), [0,-0.5; 0.5,-0.5; Inf,-Inf]));
 assert (e, [0,1; 2,3; 0,0]);
!!!!! test failed

       NaN -     NaNi       NaN -     NaNi
NaNs don't match  

4. ***** test
 [v, i] = sort ([NaN, 1i, -1, Inf, 1, 1i]);
 assert (v, [1, 1i, 1i, -1, Inf, NaN])
 assert (i, [5, 2, 6, 3, 4, 1])
!!!!! test failed
assert (i,[5, 2, 6, 3, 4, 1]) expected
   5   2   6   3   4   1
but got
   5   6   2   3   4   1
values do not matchshared variables {
  m2 =

     1   2
     3   4

  flo = 0
  fhi = Inf
}

Sorry, I do not have enough knowledge to overcome this issue.

Any ideas?
