arrayCopy confusion

Programming Questions
Hi,
When I run the following code:
float[][] X={{1,2,3},{4,5,6}}; //initialize X
float[][] Y=new float[2][3]; //initialize Y
arrayCopy(X,Y); //copy X to Y
println(Y[0][0]); //print the first value in Y
X[0][0]=Y[1][0]; //change the first value in X
println(Y[0][0]); //print the first value in Y (again).
The first print command gives a 1, and the second gives a 4. So a value in Y has changed! I'm racking my brains trying to figure out how this can be. Any help would be much appreciated.
thanks, :-)

simple question about double precision

The following code:
double x = 0.1;
println(x);
causes a display of the following value:
0.10000000149011612
Does anyone know what's causing the "149011612"? Is it a problem with println()? Is there any way to specify values to high precision?
any help much appreciated,
~Patch
