On the other hand, a signed integer can hold both negative and positive numbers. To be able to represent all of them, it uses the two’s complement form. The most significant bit represents the sign (0 for positive, 1 for negative numbers) To convert a positive value to its negative co...
program. If you can locate in memory and invert the bits of an integer of some other program, or function of a program, depending on the situation and how the program may respond, you could tell if that integer went from positive to negative, or to a drastically different positive number...

digital system. In a binary number, the leftmost bit is the Most Significant Bit or MSB. Generally, In signed binary number, this MSB is used to denote the sign, i.e {eq}1 {/eq} for negative and {eq}0 {/eq} for positive. This...
so unsigned 64-bit data can overflow it. I think decimal/numeric can store wider data if set up properly, but it's significantly less efficient than any of the basic integer types. You should ask the developers if they intend on using the full range of an unsigned 64-bit integer--the...
A binary number system is a notation in base-2. There are two bits called either 1 or 0 in the binary system. Each digit in a binary system is either 1 or 0. The bit in the binary number indicates the positional value of radix-2. A binary number ...

can someone explain me, what is the meaning of this row from the code below : "String s = Integer.toHexString( digest[i] & 0xFF );" , what is digest[i] & 0xFF. When to use byte and when to use int ? whether the both is same ? if i print out the byte = 20; is the sam...
