Matrix4x4 getcolumn/row doesn't match it's own float array

I have an issue where the GetColumn and GetRow and even printing the matrix itself doesn’t return the data that’s in it’s float array.

The float array is this:

0.9999999,0,0,4.00131E-07,0,0.9999999,0,0,0,0,0.9999999,0,0,0,0,1

And the matrix/getcolumn/getrow all display data from this data set:

1.00000	0.00000	0.00000	0.00000
0.00000	1.00000	0.00000	0.00000
0.00000	0.00000	1.00000	0.00000
0.00000	0.00000	0.00000	1.00000

Here’s my code:

string f = "";
Matrix4x4 m4 = new Matrix4x4();
for (int i = 0; i < 16; i++){
    m4 <em>= bindShapeMatrix_; //bindShapeMatrix *is a float*_</em>

f += “,” + m4*;*
}
Debug.Log(“m4:” + m4);//this returns data I didn’t put in the matrix
Debug.Log(“m4c:” + m4.GetColumn(0));//this returns data I didn’t put in the matrix
Debug.Log(“m4r:” + m4.GetRow(0)); //this returns data I didn’t put in the matrix
Debug.Log(“floats:” + f); //This is what I should have stored in the matrix
Any idea’s what I’m missing out on?

All of the 0.9999999 values will round to 1.00000. Count the number of digits, and this will be clear (7 for the first, 5 for the second). Then the 4.00131E-07 is a very small value that will round to 0. It's actually 0.000000400131 (go here to learn about Scientific Notation: http://en.wikipedia.org/wiki/Scientificnotation#Enotation ). If what you want is for it to display the full value, you'll have to use custom formatting, but if it's just debug information, I wouldn't waste the effort.
