This is another way of expressing 289627000000 or 289 627 000 000 (South African/continental notation?) or 289,627,000,000. The E part means "times 10 to the power of" the number that follows, and can be positive or negative; so E+11 means *10^11. The E notation is used for particularly large or small numbers and is often referred to as scientific notation. E followed by a negative number is a number less than 1, i.e., a fraction. So 0.001 (0,001) is 1E-3.
