See: 
RBw.d Informat in
SAS Language Reference: Dictionary


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 (floatingpoint) notation. Numeric data for scientific calculations
are often stored in floatingpoint notation. (SAS stores all numeric values
in floatingpoint notation.) A floatingpoint 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 floatingpoint binary data directly from
a terminal, but many programs write floatingpoint binary
data.
