  2. Decimal degrees - Wikipedia

    en.wikipedia.org/wiki/Decimal_degrees

    A value in decimal degrees to 5 decimal places is precise to 1.11 metres (3 ft 8 in) at the equator. Elevation also introduces a small error: at 6,378 metres (20,925 ft) elevation, the radius and surface distance is increased by 0.001 or 0.1%.

    If an unknown weight W is balanced with 3 (3 1) on its pan and 1 and 27 (3 0 and 3 3) on the other, then its weight in decimal is 25 or 10 1 1 in balanced base-3. 10 1 1 3 = 1 × 3 3 + 0 × 3 2 − 1 × 3 1 + 1 × 3 0 = 25.

    Whether or not a rational number has a terminating expansion depends on the base. For example, in base-10 the number 1/2 has a terminating expansion (0.5) while the number 1/3 does not (0.333...). In base-2 only rationals with denominators that are powers of 2 (such as 1/2 or 3/16) are terminating.

  7. Round-off error - Wikipedia

    en.wikipedia.org/wiki/Round-off_error

    A floating-point number system is normalized if the leading digit is always nonzero unless the number is zero. [3] Since the significand is d 0 . d 1 d 2 … d p − 1 {\displaystyle d_{0}.d_{1}d_{2}\ldots d_{p-1}} , the significand of a nonzero number in a normalized system satisfies 1 ≤ significand < β p {\displaystyle 1\leq {\text ...

  8. Decimal representation - Wikipedia

    13 = 0.33333... 1 ⁄ 7 = 0.142857142857... 1318 ⁄ 185 = 7.1243243243... Every time this happens the number is still a rational number (i.e. can alternatively be represented as a ratio of an integer and a positive integer). Also the converse is true: The decimal expansion of a rational number is either finite, or endlessly repeating.
