Description broy2 CLA 2011-11-15 16:22:02 EST 
Javascript is rounding when converting float to decimal.  
It should be truncating.

Use EUnit to run:

library truncate
	myFloat float;
	myDecimal decimal(12,6);
	function functionName() {@Test}	
		myFloat = 1.5663225538310885;
		myDecimal = myFloat;
		LogResult.assertDecimalEqual1(1.566322, myDecimal);
	end	
end

Runs OK in Java.  myDecimal = 1.566322
Gets failure in Javascript.  myDecimal = 1.566323

See 362834.

This causes the mathLib functions to fail running api.systemTypes in EUnit.

verified on 201111210901's build, it's successful for both java and javascript

Brenda, if this is not in eunit.test project in cvs, please add to it, so it can be used everytime we run eunit tests.
