2. Rounding - Wikipedia

   en.wikipedia.org/wiki/Rounding

   As a general rule, rounding is idempotent; [2] i.e., once a number has been rounded, rounding it again to the same precision will not change its value. Rounding functions are also monotonic; i.e., rounding two numbers to the same absolute precision will not exchange their order (but may give the same value).

3. Renard series - Wikipedia

   en.wikipedia.org/wiki/Renard_series

   The R40 numbers 3.00 and 6.00 are higher than they "should" be by interpolation, in order to give rounder numbers. In some applications more rounded values are desirable, either because the numbers from the normal series would imply an unrealistically high accuracy, or because an integer value is needed (e.g., the number of teeth in a gear).

4. Numeric precision in Microsoft Excel - Wikipedia

   en.wikipedia.org/wiki/Numeric_precision_in...

   Excel maintains 15 figures in its numbers, but they are not always accurate; mathematically, the bottom line should be the same as the top line, in 'fp-math' the step '1 + 1/9000' leads to a rounding up as the first bit of the 14 bit tail '10111000110010' of the mantissa falling off the table when adding 1 is a '1', this up-rounding is not undone when subtracting the 1 again, since there is no ...

5. Interval arithmetic - Wikipedia

   en.wikipedia.org/wiki/Interval_arithmetic

   Arithmetic work on range numbers to improve the reliability of digital systems was then published in a 1951 textbook on linear algebra by Paul S. Dwyer ; [10] intervals were used to measure rounding errors associated with floating-point numbers. A comprehensive paper on interval algebra in numerical analysis was published by Teruo Sunaga (1958).

6. Round-off error - Wikipedia

   en.wikipedia.org/wiki/Round-off_error

   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 to 0) is used.
