Width range:	2-8
Default width:	4
Decimal range:	0-10
Windows specifics:	native floating-point representation

w

specifies the width of the input field.

d

optionally specifies the power of 10 by which to divide the input value. SAS uses the d value even if the input data contain decimal points.

Details

The RBw.d informat reads numeric data that are stored in microcomputer real binary (floating-point) notation. Numeric data for scientific calculations are often stored in floating-point notation. (The SAS System stores all numeric values in floating-point notation.) A floating-point value consists of two parts: a mantissa that gives the value and an exponent that gives the value's magnitude. It is usually impossible to key in floating-point binary data directly from a terminal, but many programs write floating-point binary data.
