2. Rounding - Wikipedia

   en.wikipedia.org/wiki/Rounding

   For example, rounding x = 2.1784 dollars to whole cents (i.e., to a multiple of 0.01) entails computing 2.1784 / 0.01 = 217.84, then rounding that to 218, and finally computing 218 × 0.01 = 2.18. When rounding to a predetermined number of significant digits , the increment m depends on the magnitude of the number to be rounded (or of the ...

3. Floating-point arithmetic - Wikipedia

   en.wikipedia.org/wiki/Floating-point_arithmetic

   Alternative rounding options are also available. IEEE 754 specifies the following rounding modes: round to nearest, where ties round to the nearest even digit in the required position (the default and by far the most common mode) round to nearest, where ties round away from zero (optional for binary floating-point and commonly used in decimal)

4. Space (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Space_(mathematics)

   Neither of these words ["space" and "structure"] have a single mathematical definition. The English words can be used in essentially all the same situations, but you often think of a "space" as more geometric and a "structure" as more algebraic. [...] So you could think of "structures" as places we do algebra, and "spaces" as places we do geometry.

5. List of gravitationally rounded objects of the Solar System

   en.wikipedia.org/wiki/List_of_gravitationally...

   Mercury is round but not actually in hydrostatic equilibrium, but it is universally regarded as a planet nonetheless. [ 7 ] According to the IAU's explicit count, there are eight planets in the Solar System ; four terrestrial planets (Mercury, Venus, Earth, and Mars) and four giant planets , which can be divided further into two gas giants ...

6. Round-off error - Wikipedia

   en.wikipedia.org/wiki/Round-off_error

   The IEEE standard uses round-to-nearest. 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 ...

7. Nearest-neighbor interpolation - Wikipedia

   en.wikipedia.org/wiki/Nearest-neighbor_interpolation

   The nearest neighbor algorithm selects the value of the nearest point and does not consider the values of neighboring points at all, yielding a piecewise-constant interpolant. [1] The algorithm is very simple to implement and is commonly used (usually along with mipmapping) in real-time 3D rendering [2] to select color values for a textured ...
