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.
Range:0–10
Details
Positive integer binary
values are the same as integer binary (see the informat IBw.d Informat: Windows ), except that all values are treated as positive. Thus,
the high-order bit is part of the value rather than the value's sign.
Comparisons
The PIBw.d informat
and the IBw.d informat give you different results, and you
should differentiate carefully between these two informats. The IBw.d informat
processes both positive and negative numbers and uses the high-order
bit as the sign bit. In contrast, the PIBw.d informat is used only for
positive numbers and it does not look for a sign bit. For example,
suppose your data contain the following two-byte (byte-swapped) value:
01 80
When you read this value
using the IB2. informat, the informat looks for the sign bit, sees
that it is on, and reads the value as −32,767. However, if
you read this value with the PIB2. informat, no sign bit is used,
and the result is 32,769.
Example
Suppose your data contain
the following one-byte value:
FF
If you read this value
using the PIB1. informat, it is read as the double-precision value
255.0. Using this informat requires you to understand twos complements
and byte-swapped data format.
