So....I don't understand...how can I have a LargePositiveInteger but that is less than 32 bits? Wouldn't that be a SmallInteger?
SmallInteger maxVal hex ==> '16r3FFFFFFF'.
The largest positive two-compliment integer that fits into 32 bits is 16rEFFFFFFF, so any Integer in the range 16r4000000 through 16rEFFFFFFF is a LargePositiveInteger that can fit into a signed 32-bit C int.
Thus the number of LargePositiveInteger values that fit into a 32-bit twos-compliment representation is (16r4000000 to: 16rEFFFFFFF) size ==> 3959422976
Note that a SmallInteger is represented internally as a 31-bit value, which accounts for the difference. It's a bit confusing when you are used to thinking of 32-bit int values.
