Figure A–5 G_floating-Point Data Representation 15 14 S 4 3 EXPONENT 0 FRACTION :A FRACTION FRACTION FRACTION 63 48 ZK−1041−GE A G_floating-point value is specified by its address A, the address of the byte containing bit 0. The form of this value is sign magnitude as follows: • Bit 15 is the sign bit. • Bits 14 through 4 are an excess 1024 binary exponent. • Bits 3 through 0 and 63 through 16 represent a normalized 53-bit fraction without the redundant most significant fraction bit. Within the fraction, bits of increasing significance go from 48 through 63, 32 through 47, 16 through 31, and 0 through 3. For More Information: • On G_floating-point range and precision (Section 2.2) A.3.2.5 T_floating-Point Numbers A T_floating-point value is represented by 8 contiguous bytes. The bits are numbered from the right 0 through 63, as shown in Figure A–6. A–22 Data Storage and Representation
