S370FRBw.d

Category:	Numeric
Alignment:	left

Syntax Description

w

specifies the width of the output field.

Default:	6
Range:	2-8

d

optionally specifies to multiply the number by 10^d.

Details

A floating-point value consists of two parts: a mantissa that gives the value and an exponent that gives the value's magnitude.

Use S370FRBw.d in other operating environments to write floating-point binary data in the same format as on an IBM mainframe computer.

Comparisons

The following table shows the notation for equivalent floating-point formats in several programming languages:

Language	4 Bytes	8 Bytes
SAS	S370FRB4.	S370FRB8.
PL/I	FLOAT BIN(21)	FLOAT BIN(53)
FORTRAN	REAL*4	REAL*8
COBOL	COMP-1	COMP-2
IBM 370 assembler	E	D
C	float	double

Examples

y=put(x,s370frb6.);
put y $hex8.;

Values	Results*
-123	C2800000
*The result is a hexadecimal representation of a binary number in zoned decimal format on an IBM mainframe computer. Each two hexadecimal digits correspond to one byte of binary data, and each byte corresponds to one column of the output field.
