Basically yes. If it were -38, you'd move the decimal place the other direction, such that it would become -0.0000000...034.

so -3.4 E +38 could also be written as -3.4E39? (39 cuz the 4 comes after the decimal)

No. -3.4*10^38 (note that this is the same as -3.4E+38 it's just a slightly different, and I'd say probably more common, notation) is equivalent to -0.34*10^39.
