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.
In the IEEE standard the base is binary, i.e. =, and normalization is used.The IEEE standard stores the sign, exponent, and significand in separate fields of a floating point word, each of which has a fixed width (number of bits).
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.
Rounds (parameter 1) by (parameter 2) decimal places, and formats. Scientific notation is used for numbers greater than 1×10^9, or less than 1×10^−4. Template parameters [Edit template data] Parameter Description Type Status number 1 The number to be rounded Number required decimal places 2 The number of decimal places, if negative the number is rounded so the last (parameter 2) digits are ...
[nb 2] For instance rounding 9.46 to one decimal gives 9.5, and then 10 when rounding to integer using rounding half to even, but would give 9 when rounded to integer directly. Borman and Chatfield [15] discuss the implications of double rounding when comparing data rounded to one decimal place to specification limits expressed using integers.
Decimals between 1 and 2: fixed interval 2 −23 (1+2 −23 is the next largest float after 1) Decimals between 2 and 4: fixed interval 2 −22; Decimals between 4 and 8: fixed interval 2 −21... Decimals between 2 n and 2 n+1: fixed interval 2 n-23... Decimals between 2 22 =4194304 and 2 23 =8388608: fixed interval 2 −1 =0.5
to 2 decimal places Mean of y: 47.83 to 2 decimal places Sample variance of y: s 2 y: 26.93 to 2 decimal places Correlation between x and y: −0.06 to 3 decimal places Linear regression line y = 53 − 0.1x: to 0 and 1 decimal places, respectively Coefficient of determination of the linear regression: 0.004 to 3 decimal places
There is another phrase known in Romanian that will help to memorize the number by eight decimal places: Așa e bine a scrie renumitul și utilul număr. — "This is the way to write the renowned and useful number." Another alternative for 15 decimal places: Ion a luat o carte, biografie, în latina veche.
