Integer Confusion and :

[KeithB]

All this talking about random numbers has made me want to port the Marsenne twister to HP-PPL. Most algorithms use bit twiddling and 32 bit integers.

Given the "binary explorer" I assume that most numbers are 64 bit. Is there a way to declare a 32 bit variable/number? I see the intriguing ':' operator, but as far as I could tell, it is undocumented. (It was a bit tedious searching the manual for ':' - whoever wrote the manual sure likes his colons!)

I also see the SETBITS() command. Can I use that on a variable to make it 32 bits?
