How long is a comp-2?

COMP-2 items are 8 bytes long. The sign is contained in the first bit of the leftmost byte and the next 11 bits contain the exponent. The remaining 52 bits contain the mantissa. For conditional expressions, the class condition cannot be used for COMPUTATIONAL-2 or COMP-2 internal floating-point data items.

What is COMP 1 and COMP-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.

What is cobol COMP-2?

COMP-2 allows signed floating-point item where the sign stores on leftmost bit. COMP-2 stores the data in the format of mantissa and exponent. In this, mantissa is numeric value and exponent is the precision number.

What is comp COMP1 COMP2 COMP3 in Cobol?

COMP1: will store data in 4 bytes, floating point form and result the rounded value. COMP2 : will store the data in 8 bytes, in Hexadecimal form and results more precise value. COMP3 : It is a packed decimal usage and which occupies one digit/ half byte of the storage space.

What is Comp and Comp-3?

COMP usage stores the data in half word or in full word, depending on the size of the data. COMP3 usage stores 1 digit in half byte (i.e. 4 bits) and a separate 1 bit is reserved for the sign, which is stored at the right side of the data.

How is Comp-3 calculated?

To calculate the byte-length of a comp-3 field, start with the total number of digits and divide by 2 giving a result (discarding the remainder if any), then add 1 to the result. So, a field with “pic s9(6) comp-3” would take 4 bytes (6/2 +1).

What do you learn in English Comp 2?

English Composition II is a course designed to strengthen students’ skills as writers and to focus on analysis and argument. Assignments include critical examination of literature and an essay using research and documentation utilizing the MLA style sheet.

What is comp in mainframe?

COMP usage is a binary representation of data and stores in pure binary format. The amount of storage occupied by a binary item depends on the number of decimal digits defined in its PICTURE clause.

What is Comp 4 COBOL?

comp-4 Data comp-4 is fixed-point binary data with 15-bit precision, word-aligned, and stored in two bytes. The scaling factor is zero. Values are stored in two’s complement form. For integer data, such as counters and switches that do not require values outside the range -32,768 to +32,767, use comp-4 data.

Is COMP or COMP-3 better?

We can use only 9 and S in PIC Clause. We can use 9 , S , V in PIC Clause. COMP usage stores the data in half word or in full word, depending on the size of the data. COMP3 usage stores 1 digit in half byte (i.e. 4 bits) and a separate 1 bit is reserved for the sign, which is stored at the right side of the data.
