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.
the number 1000 (the point being a thousands separator, as common in many European countries) the number 1 known to four significant figures, i.e. 1±0.0005 (here the dot is a decimal separator, as commonly used in much of the English-speaking world)
1000 or one thousand is the natural number following 999 and preceding 1001. In most English-speaking countries , it can be written with or without a comma or sometimes a period separating the thousands digit: 1,000 .
For B = 10% one requires n = 100, for B = 5% one needs n = 400, for B = 3% the requirement approximates to n = 1000, while for B = 1% a sample size of n = 10000 is required. These numbers are quoted often in news reports of opinion polls and other sample surveys. However, the results reported may not be the exact value as numbers are preferably ...
For example, 14000 has three trailing zeros and is therefore divisible by 1000 = 10 3, but not by 10 4. This property is useful when looking for small factors in integer factorization . Some computer architectures have a count trailing zeros operation in their instruction set for efficiently determining the number of trailing zero bits in a ...
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 ...
1000 or thousand may refer to: 1000 (number), a natural number; AD 1000, a leap year in the Julian calendar; 1000 BC, a year of the Before Christ era;
Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).
