3.01 × 10 8: 3 significant figures Approximating a value by a multiple of a specified amount 48.2 45 Multiple of 15 Approximating each of a finite set of real numbers by an integer so that the sum of the rounded numbers equals the rounded sum of the numbers [nb 1]
Prices are rounded down to the nearest multiple of 5 cents for sales ending in 1¢ & 2¢ (rounded to 0¢) and 6¢ & 7¢ (rounded to 5¢). Prices are rounded up to the nearest multiple of 5 cents for sales ending in 3¢ & 4¢ (round to 5¢) and 8¢ & 9¢ (round to 10¢). Values ending in 0¢ or 5¢ remain unchanged.
Indicates the number of significant figures to be used in rounding. Number: optional: Rounding output: round: The type of rounding. “5” rounds the output number to nearest multiple of 5, “25” to nearest multiple of 25, “each” rounds each number in a range. Number: optional: Thousands separator: comma
|-N (where -N is a negative number) replaces N digits before the decimal mark with zero (round output to nearest 10 N). |sigfig=N (where N is a positive number) to specify the number of significant digits (round output to N significant figures). |round=5 to round the output to the nearest multiple of 5. The round value can be 0.5, 5, 10, 25 or ...
A round number is mathematically defined as an integer which is the product of a considerable number of comparatively small factors [12] [13] as compared to its neighboring numbers, such as 24 = 2 × 2 × 2 × 3 (4 factors, as opposed to 3 factors for 27; 2 factors for 21, 22, 25, and 26; and 1 factor for 23).
For a number written in scientific notation, this logarithmic rounding scale requires rounding up to the next power of ten when the multiplier is greater than the square root of ten (about 3.162). For example, the nearest order of magnitude for 1.7 × 10 8 is 8, whereas the nearest order of magnitude for 3.7 × 10 8 is 9.

Some numbers may have several possible floating-point representations. For instance, if b = 10, and p = 7, then −12.345 can be represented by −12345×10 −3, −123450×10 −4, and −1234500×10 −5. However, for most operations, such as arithmetic operations, the result (value) does not depend on the representation of the inputs.
