It is not a measurement, therefore, it is infinitely precise.
There is no uncertainty in the number.
When the last digit of a significant digit is 5, you always round up.
45.0300mm has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
Significant figures are basically the amount of digits in a number. E.g. 2.576 has 4 significant figures 32.545 has 5 significant figures Zeroes before the first non-zero digit and after the last non-zero digit are not counted as significant figures. E.g. 0067.4 has 3 significant figures 67.400 has 3 significant figures 0067.400 has 3 significant figures. In case of thermometer measurement of normal temperatures maximum three digits are significant because most of the thermometers indicate one digit after decimal; as 37.4.
If you are rounding a 4 digit number to 3 significant figures, then you're rounding to the nearest ten. The 4th digit is 7, so since this digit is >= 5, you should round up the 3rd digit. 1467 becomes 1470. In scientific notation you would express this as 1.47 x 103 to make it clear that there are only 3 significant figures.
There are three significant figures in 25.0 because the trailing zero is not a placeholder digit. ~foxy
When the last digit of a significant digit is 5, you always round up.
It is 124.68 rounded to 5 significant figures
The first significant digit is the 5, which is in the ten-thousandth's position.
All digits are significant in this case. Any digit after a decimal point is a significant digit.
The 5.
Every digit in 40.725 is significant, so there are 5
Starting at the second digit after the decimal, if it is between 0 and 4, you round the first digit down. If it is between 5 and 9, you round it up. If the third digit is between 0 and 4, you round the second digit down. If it is between 5 and 9, you round the second digit up. Rounded to.......... 1 signifcant figure: .3 2 significant figures: .29 3 significant figures: .294 4 significant figures: .2943 5 significant figures: .29430
5, the only thing that is not considered a sign digit is a leading zero EG: 0.456 it will have 3 sign digit the 0. doesnt count as a sign digit
Three significant figures. The two zeroes after the digit 5 are irrelevant.
5. The zeros preceding (before) the 5 are place-holders and are not significant figures. However, the zero at the end indicates the level of accuracy and so IS a significant digit.
45.0300mm has six significant figures. A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant.
To round a number to a particular digit, look at the digit immediately to the right of your target, in this case, the fourth significant figure. If that digit is 4 or lower, zero it and everything to the right of it out. If that digit is 5 or higher, increase the target digit by one and zero everything to the right of it out. If your target digit is a 9, increasing it will turn it to zero and increase the digit to the left of it by one.
