Check the digit in the fourth position, which is a 9. This will cause a rounding up, giving 14.7500 as the answer.
To convert the number 0.004758 to three significant figures, we need to round it off appropriately. Identify the significant figures: The given number, 0.004758, has 5 significant figures. Determine the significant figures based on the three most significant digits: The three most significant digits in 0.004758 are 4, 7, and 5. Round the number: Look at the digit immediately after the third significant figure, which is 7. Since 7 is 5 or greater, we round up the third significant figure (5). Apply rounding: The number rounded to three significant figures is 0.00476. Therefore, 0.004758 rounded to three significant figures is **0.00476**.

If the last three digits of any number are equal to or greater than 500, then you round up to the nearest 1000. For example, the number 2573 rounds up to 3000. If the last three digits of any number are equal to or less than 499, then you round down to the nearest 1000. For example, the number 2473 rounds down to 2000. This assumes you are 'rounding up' which is the usual meaning of 'rounding'
The answer depends on the data source. Exchange rates are usually accurate to 6 significant digits.
Keep the first three digits, replace the remaining digits with zero - rounding up or down as appropriate.
It's called 'rounding' - either up or down.
For a quick estimate, you would usually round to one, sometimes to two, significant digits. One significant digit means discarding all digits after the first, i.e., converting them to zero (and rounding the remaining digit up or down as appropriate).
It would be 50. In rounding up, we add one and truncate the digits after the decimal point. In rounding down, we just truncate the digits. http://en.wikipedia.org/wiki/Rounding#Common_method
After determining whether to round up or down, the digits, to the right of the place, are discarded.
The maximum number of significant digits in value belonging to the double type is 15. The maximum number of significant digits is called the precision.
3078 to three significant figures is 3080. When rounding to three significant figures, the digit in the hundreds place (0) remains the same, while the digits after it (7 and 8) are greater than 5 so it is rounded up.
Rounding numbers means adjusting the digits (up or down) to make rough calculations easier. The result will be an estimated answer rather than a precise one
To round numbers to 3 significant figures, identify the first three non-zero digits from the left. If the digit after the third significant figure is 5 or more, round up the last significant figure. If the digit after the third significant figure is less than 5, keep the last significant figure the same. Trailing zeroes can be kept to maintain the significant figures.
The first 3 significant digits of a number are the first 3 digits starting from the left ignoring any leading zeros. So 31456 = 31500 (3 significant digits) The 5 in the "56" rounds the 4 up.
To round to 3 significant digits, start counting from the first non-zero digit. If the digit to the right of the third significant digit is 5 or greater, round up. If the digit is less than 5, leave the third significant digit unchanged. Replace all digits to the right of the third significant digit with zeros.
The number of significant figures in a number is equal to the number of digits to the left of the decimal point up to the first leading zero. It is then added to the number of total digits to the right of the decimal point. In this case, there are six significant digits.
