    In topology and in calculus, a round function is a scalar function, over a manifold, whose critical points form one or several connected components, each homeomorphic to the circle, also called critical loops. They are special cases of Morse-Bott functions.

  3. Round (cryptography) - Wikipedia

    en.wikipedia.org/wiki/Round_(cryptography)

    Since a single round is usually cryptographically weak, many attacks that fail to work against the full version of ciphers will work on such reduced-round variants. The result of such attack provides valuable information about the strength of the algorithm, [9] a typical break of the full cipher starts out as a success against a reduced-round ...

  4. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    If x is negative, round-down is the same as round-away-from-zero, and round-up is the same as round-toward-zero. In any case, if x is an integer, y is just x . Where many calculations are done in sequence, the choice of rounding method can have a very significant effect on the result.

    en.wikipedia.org/wiki/Round-off_error

    Round-by-chop: The base-expansion of is truncated after the ()-th digit. This rounding rule is biased because it always moves the result toward zero. Round-to-nearest: () is set to the nearest floating-point number to . When there is a tie, the floating-point number whose last stored digit is even (also, the last digit, in binary form, is equal ...

  6. Round number - Wikipedia

    en.wikipedia.org/wiki/Round_number

    A round number is an integer that ends with one or more "0"s (zero-digit) in a given base. [1] So, 590 is rounder than 592, but 590 is less round than 600. In both technical and informal language, a round number is often interpreted to stand for a value or values near to the nominal value expressed.
