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 ...
Thus, a representation that compresses the storage size of a file from 10 MB to 2 MB yields a space saving of 1 - 2/10 = 0.8, often notated as a percentage, 80%. For signals of indefinite size, such as streaming audio and video, the compression ratio is defined in terms of uncompressed and compressed data rates instead of data sizes:
This template simulates decimal-alignment for a table cell by splitting a decimal number to place integer and fractional portions into two separate cells and minimizing the space between those cells. See Help:Table#Decimal point alignment for more information.
cells to perform alignment on leftx (optional, x = 1 to 10) alignment of the decimal point within column x, as a percentage of cell width left (optional) default alignment of the decimal point if no "leftx" argument is given (defaults to 50%)
0.00034 has 2 significant figures (3 and 4) if the resolution is 0.00001. Zeros to the right of the last non-zero digit (trailing zeros) in a number with the decimal point are significant if they are within the measurement or reporting resolution. 1.200 has four significant figures (1, 2, 0, and 0) if they are allowed by the measurement resolution.
For example, while a fixed-point representation that allocates 8 decimal digits and 2 decimal places can represent the numbers 123456.78, 8765.43, 123.00, and so on, a floating-point representation with 8 decimal digits could also represent 1.2345678, 1234567.8, 0.000012345678, 12345678000000000, and so on.
Pixel aspect ratio 1:1 Pixel aspect ratio 2:1. A Pixel aspect ratio (often abbreviated PAR) is a mathematical ratio that describes how the width of a pixel in a digital image compared to the height of that pixel. Most digital imaging systems display an image as a grid of tiny, square pixels.
Integers between 2 24 =16777216 and 2 25 =33554432 round to a multiple of 2 (even number) Integers between 2 25 and 2 26 round to a multiple of 4... Integers between 2 n and 2 n+1 round to a multiple of 2 n-23... Integers between 2 127 and 2 128 round to a multiple of 2 104; Integers greater than or equal to 2 128 are rounded to "infinity".
