    Omission of the low-order bit of the divisor polynomial: Since the low-order bit is always 1, authors such as Philip Koopman represent polynomials with their high-order bit intact, but without the low-order bit (the or 1 term). This convention encodes the polynomial complete with its degree in one integer.

    Subsequently the 32-bit versions were hard to get. Except for embedded systems with their special programs, the consideration of varying large-file support becomes obsolete in program code after 2020. Related problems. The year 2038 problem is well known for another case where a 32-bit "long" on 32-bit platforms will lead into problems. Just ...

  8. Bit numbering - Wikipedia

    en.wikipedia.org/wiki/Bit_numbering

    This bit numbering method has the advantage that for any unsigned number the value of the number can be calculated by using exponentiation with the bit number and a base of 2. [ 2] The value of an unsigned binary integer is therefore. where bi denotes the value of the bit with number i, and N denotes the number of bits in total.
