An unsigned, fixed-width integer type can represent values from 0 through (2 ** bit, where ** is exponentiation. A signed, fixed-width integer type can represent values from -(2 ** (bit through (2 ** (bit. For example, the Int8 type has a bit value of 8 and can store any integer in the range -128...127.
