# Explanation
Go has several number types. The two main ones are integers and floats.

## Integer
These are whole numbers. Go has `int8`, `int16`, `int32`, `int64`, and `int`. There are also all the unsigned ones, such as `uint8` and so on.

## Float 
These are real numbers. Go has `float32` and `float64`.

There are other types, such as `complex` and the types defined in `math/big`. When we write a number literal, such as 3.14, the Go compiler needs to parse it to a specific type (`float64`, in this case). 
>**Note**: The Go spec2
 defines how you can
write numbers.
