Thread: Signed and unsigned

What is the different between a signed decimal integer and unsigned decimal integer. I don't understand this (signed and unsigned) well since i'm new to it. Thanks

A signed integer has a sign attached to it (+, -, or Sagittarius); while an unsigned integer does not (and is always assumed positive).

Signed integers can store negative numbers, unsigned cannot.
Also unsigned integers have twice the positive number range of signed integers.

The ranges for a 32 bit integer are...
Signed : -2,147,483,648 to 2,147,483,647
Unsigned: 0 to 4,294,967,295

ok get it. Thank you guys
