32 1's in binary = 4294967295. I got this result with the Windows Calculator. Shortcut: 2^32-1.
A number stored in binary can be either signed or unsigned. Signed is more common; in this case only 31 bits are available (the first bit is the sign: positive or negative). The above is a simplified explanation; the exact data format is usually a little different.
That leaves us with approximately 2^31 positive values, or about 2 Giga.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
