This is it! The final email in my 2+ year series on the Go spec. Today we cover the last ~paragraph of the spec, not accounting for the appendix, which is mostly just a history of major changes to the spec. Size and alignment guarantees For the numeric types, the following sizes are guaranteed: type size in bytes byte, uint8, int8 1 uint16, int16 2 uint32, int32, float32 4 uint64, int64, float64, complex64 8 complex128 16 Most notably, int is omitted from this list.
