Numeric
Integers
Integer sizes are expressed by their bit-size.
signed
int // (however many bits your CPU word-size is) int8 // 128 - 127 int16 // 32,768 - 32,767 int32 // 2,147,483,648 - 2,147,483,647 int64 // 9,223,372,036,854,775,808 - 9,223,372,036,854,775,807unsigned

Same as
uint8
.math/big
Slow, but handles numbers of any size.
Pointers
uintptr // a pointer of however many bits your CPU word-size is
