pow function

[GoogleCodeExporter]

What steps will reproduce the problem?
1. (new BigDecimal("2")).pow(new BigDecimal("3")); 

What is the expected output? What do you see instead?
I expect 8. 1 is returned.

What version of the product are you using? On what operating system?
The latest 2.0.3

Please provide any additional information below.
I guess your pow method isn't functionnal.

Thank you. Your library is the best I've seen.

Marco, from what I can tell this is actually not fixed in the 2.1 release. 
BigDecimal
is a port from the Java class of the same name. However the power function 
depends
upon an integer overflow which will not occur in javascript:

2405   n=n+n; // shift left 1 bit
2406   if (n<0)

I got in touch with the original author, he provided the fix below:
2405   n<<=1; // shift left 1 bit
2406   if (n<0)

Hope this helps,
Matt
