What is the difference between comp-1 and 2?

COMP-1 refers to short (single-precision) floating-point format, and COMP-2 refers to long (double-precision) floating-point format, which occupy 4 and 8 bytes of storage, respectively. The leftmost bit contains the sign; the next seven bits contain the exponent; the remaining 3 or 7 bytes contain the mantissa.

How is comp variable stored in COBOL?

COBOL has what you might call “decimal-binary” fields (COMP and siblings). That is, the data is stored as binary but its maximum and minimum values are the number and full value of the PICture clause which is used in the definition. COMP PIC 9 – can contain zero to nine.

What is the size of Comp field in COBOL?

COBOL – COMP fields. 1 COMP and COMP-4 are also same as binary format. 2 It occupies 2 or 4 or 8 bytes of storage. 3 If the data item is signed,leftmost bit is used to represent sign. 4 Four or less decimal digits occupy 2 bytes. 5 Five to nine digits occupy 4 bytes. 6 10 to 18 decimal digits occupy 8 bytes.

What are the different types of internal forms in COBOL?

COMP COMP-1 COMP-2 COMP-3 COMP:Normally, a computer can store data in more than one internal form. In COBOL, a programmer is allowed to specify the internal form of the data item so as to facilitate its use in the most efficient manner. There are only two general forms of internal representation namely COMPUTATIONAL and DISPLAY.

What is the difference between comp-1 and comp-2?

The advantage is that this increases the precision of the data, which means that more significant digits are available. Similar to COMP-1, The PICTURE Clause cannot be specified for COMP-2 items also. COMP-1 takes 8 bytes of storage.COMP-2 is more precision than COMP-1.

What is comp-5 data type?

COMPUTATIONAL-5 or COMP-5 (native binary) These data items are represented in storage as binary data. The data items can contain values up to the capacity of the native binary representation (2, 4, or 8 bytes), rather than being limited to the value implied by the number of nines in the picture for the item (as is the case for USAGE BINARY data).
