  2. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    Some programming languages (such as Java and Python) use "half up" to refer to round half away from zero rather than round half toward positive infinity. [ 4 ] [ 5 ] This method only requires checking one digit to determine rounding direction in two's complement and similar representations.

  3. Java syntax - Wikipedia

    en.wikipedia.org/wiki/Java_syntax

    A snippet of Java code with keywords highlighted in bold blue font. The syntax of Java is the set of rules defining how a Java program is written and interpreted. The syntax is mostly derived from C and C++. Unlike C++, Java has no global functions or variables, but has data members which are also regarded as global variables.

  4. RRDtool - Wikipedia

    en.wikipedia.org/wiki/RRDtool

    RRDtool has a graph function, which presents data from an RRD in a customizable graphical format. RRDtool (round-robin database tool) aims to handle time series data such as network bandwidth, temperatures or CPU load. The data is stored in a circular buffer based database, thus the system storage footprint remains constant over time.

  5. Round-off error - Wikipedia

    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. Talk:Rounding - Wikipedia

    en.wikipedia.org/wiki/Talk:Rounding

    Yes, and this is why "round ties to odd" is not part of standard IEEE-754 rounding modes (so it has no native support in x87 FPUs), and also explains why "round ties to even" is the default mode for floatting points in ANSI C, C++, Java, and many other languages supporting or using floatting point types (including Javascript, despite Javascript ...

  7. Salsa20 - Wikipedia

    en.wikipedia.org/wiki/Salsa20

    It uses a new round function that increases diffusion and increases performance on some architectures. [ 4 ] Both ciphers are built on a pseudorandom function based on add–rotate–XOR (ARX) operations — 32-bit addition, bitwise addition (XOR) and rotation operations.

  8. Round function - Wikipedia

    en.wikipedia.org/wiki/Round_function

    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.

  9. 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.
