COMPUTATIONAL or COMP Representation of the COMPUTATIONAL phrase is system-dependent and is normally assigned to representations that yield the greatest efficiency when arithmetic operations are performed on that system.
For the VS COBOL II compiler, the COMPUTATIONAL phrase is synonymous with BINARY.
COMPUTATIONAL-1 or COMP-1
Specified for internal floating-point items (single precision).
COMP-1 items are 4 bytes long. The sign is contained in the first bit
of the leftmost byte and the exponent is contained in the remaining 7
bits. The last 3 bytes contain the mantissa.
COMPUTATIONAL-2 or COMP-2
Specified for internal floating-point items (double precision).
COMP-2 items are 8 bytes long. The sign is contained in the first bit
of the leftmost byte and the remaining 7 bits contain the exponent.
The remaining 7 bytes contain the mantissa.
COMPUTATIONAL-3 or COMP-3 (internal decimal)
For VS COBOL II, this is the equivalent of PACKED-DECIMAL.
COMPUTATIONAL-4 or COMP-4 (binary)
For VS COBOL II this is the equivalent of BINARY. |
