A computer uses an 8-bit floating-point representation consistent with IEEE 754 normalized format. It is identical to the 32-bit and 64-bit formats in terms of the meaning of fields and special encodings. The format includes 1 sign bit, 4 exponent bits, and 3 mantissa (magnitude or fraction) bits. As in IEEE 754, 0000 and 1111 in exponent field are reserved.The exponent field employs an excess-7 coding.

The following table gives the 8-bit Excess-7 representation.

Decimal	0	1	2	3	4	5	6	7
Unsigned	0000	0001	0010	0011	0100	0101	0110	0111
Excess-7	Reserved	-6	-5	-4	-3	-2	-1	0

Decimal	8	9	10	11	12	13	14	15
Unsigned	1000	1001	1010	1011	1100	1101	1110	1111
Excess-7	1	2	3	4	5	6	7	reserved
