|
-
w
-
specifies the width of the input field.
-
d
-
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.
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. (SAS 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.
