How to round a 5 digit number to 3 significant figures?
For instance: If there is a need to round a 5 digit number to 3 significant figures (sig figs), then all you need to drop the last 2 digits and simply round off the last digit of the remaining number. To get a proper idea, let’s look at the given example of how you can round off a 4 digit number to 3 significant figures (sig figs).
How many significant numbers are there in 4.000?
Thus, 4.000 has 4 significant figures. RULE #4 – A zero used to fix a decimal point is never significant. The quantities 0.456, 0.0456 and 0.00456 all contain 3 significant figures. In this case, you need to think in terms of exponential numbers.
How many SIG Figs have an unlimited number of significant figures?
60 have an unlimited number of sig figs as rule depicted that all exact numbers have an unlimited number of significant figures. How many sig figs is 35? If you counted the number of individuals in the office to be exactly 35, then it’s clear that 35 would have an unlimited number of significant figures.
