Simple Question just to confirm. A method returns a Long, that long may be made up of leading zeros. What are the rules on this. Are the zeros wiped off when it's passed back or do they stay.
Ahh I realised where this gets more complexed I am currently using this method to add values to a database, it returns a LONG. Android SQLiteDatabase.Insert
So I'm wondering if it returns something with a leading zero what's stopping it being chopped off?
No integral type (or floating point type) preserves leading zeros. In binary, there is no concept of 00
vs 0
(nor in a mathematical sense).
System.out.println(Long.toBinaryString(Long.parseLong("001")));
System.out.println(Long.toBinaryString(Long.parseLong("1")));
Is just going to display 1
for both.
