Now, it computes the numbers with only basic arithmetic operations, without first creating a string and then calling parseFloat. The new function doesn't behave exactly the same as the old one. In particular, the old behaviour was that when there was a number immediatly followed by an 'E', the 'E' was consumed. Now it's not. It allows for "glued" numbers and operators. Also, the new function is faster and consumes less memory.
