about the problem of double primitive type

[ygxinqing]

Recently, I transplant lejos to the development board of mini2440. I use the cross compiler is arm-linux-gcc-4.3.2. I find a problem of double primitive type.
For example:
the Java program is:
long l = 900;
double d1 = 900.0;
double d2 = 0.900;
LCD.drawString( "l=" + l + "\n", 0, 0 );
LCD.drawString( "d1=" + d1 + "\n", 0, 0 );
LCD.drawString( "d2=" + d2 + "\n", 0, 0 );

the result is:
l=900
d1=000.0
d2=0.00000000000001E260

This matter is too strange! If I use the cross complier arm-linux-gcc-3.4.1, do not have this problem.
But my mini2440 development board can only use the arm-linux-gcc-4.3.2 cross complier

Who can tell me the reason? Thanks very much!

No real idea, possibly the way that doubles are stored in memory has been changed between the two versions? Seem to remember that the memory layout for doubles was a little odd. What results do you get if you change the code to be
double d2 = l1;

We use gcc 4.3.2 to build the NXT firmware. And we don't have any problems with the float/double format. So I don't have any idea either.

What Arm chip is used in the mini2440? Does it have any sort of fp unit?
