 Float types have the `float32` and `float64` types and no type called `float`. The latter one is the default type if using brief statement.
 
-That's all? No! Go supports complex numbers as well. `complex128` (with a 64-bit real and 64-bit imaginary part) is the default type, if you need a smaller type, there is one called `complex64` (with a 32-bit real and 32-bit imaginary part). Its form is `RE+IMi`, where `RE` is real part and `IM` is imaginary part, the last `i` is imaginary number. There is a example of complex number.
