What is the endianness of your platform?  I think that the big endian code in

This smells to me like the tag and payload getting flipped around, which might 
happen if there are parts of the code that are assuming little endian and your 
hardware is big endian.

Javascript code of test case

  var tmp = -1*0;

  debug("tmp:" + tmp); 

  var result = tmp + 1;

  debug("The result should be 1,result:" + result);   //print

  var item1 =  result - 1;

  debug("The item1 should be 0,item1:" + item1); //print

And the log information are:

[CONSOLE-DEBUG]Message is :'tmp:0'

[CONSOLE-DEBUG]Message is :'The result should be 1,result:0.0078125'

[CONSOLE-DEBUG]Message is :'The item1 should be 0,item1:0'

[CONSOLE-DEBUG]Message is :'The item2 should be -1,item2:-0.0078125'
