Representation of Floating-Point Numbers

Three possible representations for a 3-bit exponent: a magnitude only representation, in which the represented numbers are 0-7; a sign & magnitude representation, in which the numbers are 0, 1, 2, 3, -0, -1, -2, and -3; and an excess-3 (bias of 3) representation, in which the represented numbers are -3 to +4.
