java Programming Glossary: two'sHow are integers internally represented at a bit level in Java? http://stackoverflow.com/questions/13422259/how-are-integers-internally-represented-at-a-bit-level-in-java is are all integers positive and negative stored as two's complement or are only negative numbers in two's complement.. stored as two's complement or are only negative numbers in two's complement I see that the specs says x bit two's complement.. in two's complement I see that the specs says x bit two's complement number . But I often get confused. For instance int..
Why is the range of bytes -128 to 127 in Java? http://stackoverflow.com/questions/3621067/why-is-the-range-of-bytes-128-to-127-in-java java byte share improve this question The answer is two's complement . In short Java and most modern languages do not.. negative integers are represented in a system called two's complement which allows easier arithmetic processing in hardware.. the bottom of the range. Another interesting property of two's complement systems is that the first bit does effectively function..
What is the difference between the float and integer data type when the size is the same? http://stackoverflow.com/questions/4806944/what-is-the-difference-between-the-float-and-integer-data-type-when-the-size-is is in Java and many computers too done in the so called two's complement . This basically means that you can represent the..
Why is (-1 >>> 32) = -1? [duplicate] http://stackoverflow.com/questions/4813909/why-is-1-32-1 the underlying binary representation of integers e.g. two's complement as well as the number of bits e.g. 32 . Each programming..
Why if (n & -n) == n then n is a power of 2? http://stackoverflow.com/questions/7405438/why-if-n-n-n-then-n-is-a-power-of-2 two then n in binary is a single 1 followed by zeros. n in two's complement is the inverse 1 so the bits lines up thus n 0000100...000.. n n 0000100...000 To see why this work consider two's complement as inverse 1 n ~n 1 n 0000100...000 inverse n 1111011...111.. 1 n ~n 1 n 0000100...000 inverse n 1111011...111 1 two's comp 1111100...000 since you carry the one all the way through..
How does Java convert int into byte? http://stackoverflow.com/questions/842817/how-does-java-convert-int-into-byte in Java is signed and bytes ints longs are encoded in two's complement. In this number scheme the most significant bit specifies.. the 1 to the left 24 times. Now one way to read a negative two's complement number is to start with the least significant bit..
Java long number too large error? http://stackoverflow.com/questions/8924896/java-long-number-too-large-error to min and max long The long data type is a 64 bit signed two's complement integer. It has a minimum value of 9 223 372 036..
why Integer.MAX_VALUE + 1 == Integer.MIN_VALUE? http://stackoverflow.com/questions/9397475/why-integer-max-value-1-integer-min-value mathematical sum as represented in some sufficiently large two's complement format. If overflow occurs then the sign of the result..
