  3. 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%.

  4. Decimal - Wikipedia

    en.wikipedia.org/wiki/Decimal

    A repeating decimal is an infinite decimal that, after some place, repeats indefinitely the same sequence of digits (e.g., 5.123144144144144... = 5.123 144). [4] An infinite decimal represents a rational number , the quotient of two integers, if and only if it is a repeating decimal or has a finite number of non-zero digits.

  5. Fractional part - Wikipedia

    en.wikipedia.org/wiki/Fractional_part

    The fractional part or decimal part [1] of a non‐negative real number is the excess beyond that number's integer part. The latter is defined as the largest integer not greater than x, called floor of x or . Then, the fractional part can be formulated as a difference : . For a positive number written in a conventional positional numeral system ...

    log 10 (3.000 × 10 4) = log 10 (10 4) + log 10 (3.000) = 4.000000... (exact number so infinite significant digits) + 0.477 1 212547... = 4.477 1 212547 ≈ 4.4771. When taking the antilogarithm of a normalized number, the result is rounded to have as many significant figures as the significant figures in the decimal part of the number to be ...

    1.5 × 10 −157 is approximately equal to the probability that in a randomly selected group of 365 people, all of them will have different birthdays. [3] 1 × 10 −101 is equal to the smallest non-zero value that can be represented by a single-precision IEEE decimal floating-point value.

  9. p-value - Wikipedia

    en.wikipedia.org/wiki/P-value

    The p -value is used in the context of null hypothesis testing in order to quantify the statistical significance of a result, the result being the observed value of the chosen statistic . [ note 2] The lower the p -value is, the lower the probability of getting that result if the null hypothesis were true. A result is said to be statistically ...
