    = 2.80000 - 2.75987 As expected, the low-order parts can be retained in c with no or minor round-off effects. = 0.0401300 In this iteration, t was a bit too high, the excess will be subtracted off in next iteration. sum = 10005.9 Exact result is 10005.85987, sum is correct, rounded to 6 digits.

  3. Rounding - Wikipedia

    en.wikipedia.org/wiki/Rounding

    For example, 1.6 would be rounded to 1 with probability 0.4 and to 2 with probability 0.6. Stochastic rounding can be accurate in a way that a rounding function can never be. For example, suppose one started with 0 and added 0.3 to that one hundred times while rounding the running total between every addition.

    en.wikipedia.org/wiki/Round-off_error

    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 to 0) is used.

  5. Knuckle thread - Wikipedia

    en.wikipedia.org/wiki/Knuckle_thread

    Knuckle threads with a flat 30 degree flank thread angle are standardized in DIN 405 for inch pitches and diameters ranging from 8 mm to 200 mm. [3] A more recent standard DIN 20400 uses metric thread pitch and lists diameters from 10 mm to 300 mm. [4] As DIN is a German organization, many instances of the DIN thread charts [5] write numbers with a comma as the decimal marker.

  6. Round number - Wikipedia

    en.wikipedia.org/wiki/Round_number

    In decimal notation, a number ending in the digit "5" is also considered more round than one ending in another non-zero digit (but less round than any which ends with "0"). [2] [3] For example, the number 25 tends to be seen as more round than 24. Thus someone might say, upon turning 45, that their age is more round than when they turn 44 or 46.

    Excess-3, 3-excess [1] [2] [3] or 10-excess-3 binary code (often abbreviated as XS-3, [4] 3XS [1] or X3 [5] [6]), shifted binary [7] or Stibitz code [1] [2] [8] [9] (after George Stibitz, [10] who built a relay-based adding machine in 1937 [11] [12]) is a self-complementary binary-coded decimal (BCD) code and numeral system. It is a biased ...

  9. Zander - Wikipedia

    en.wikipedia.org/wiki/Zander

    The zander spawns over gravel in flowing water, the males defend a territory in which they dig shallow depressions in sand or gravel which are roughly 50 centimetres (20 in) across and 5–10 centimetres (2.0–3.9 in) in depth in sand or gravel. They will also nest among exposed plant roots and the eggs are laid onto these roots.
