could someone please tell me, what that should bring! Are we talking about
characters or integers (I understand something numeric by INTEGER!).
You might understand it or not: there is nothing like INTEGER in SAS! The
only numeric type in SAS is FLOAT BINARY.
Representating something like an integer requires something like BCD (Binary
Coded Decimal) where each number is coded. You have a half-byte for each
digit, so you can represent something like 11 (that should be an integer)
with 1 Byte (not really, because you might need also negative values, so
another half-byte for the sign.
In float binary that is always internal something like 1.1 * 10e1. If you
are converting a num to char, it is only a question with which format you do
that. The default might be best8. or something like that. Use 8.2 and you'll
find your dot.
Again: it's seseless to ask for type INTEGER in SAS if there is none!
