e-2 = 0.1353
to the 4th # before the decimal point
0.036089457 to four decimal places (4 places of precision) is 0.0361. The number at the 5th decimal place (8) is used to round *up* the 4th decimal place figure from 0 to 1. If the number at the 5th decimal place had been
6.287 ( since the 4th decimal is less than 5 we round down)
You first look at the third decimal place. In this case it is 7. Then you look at the decimal place after that (the 4th one) and if it larger or equal to 5, then you round up. If it is 4 or smaller, then you leave it be. So in this one 55.06756 = 55.068 to 3 decimal places.
16.7049 to 3dp is 16.705. The 4th decimal place decided whether to round up, or not, the first three places. The 4th dp in this case is 9, so it rounds up.
It is: 91.6456 to the nearest ten thousandths
79.0 has three significant figures - as trailing zeros after a decimal point are not usually written, to have been written the zero must have significance. Thus 9174.48 needs to be rounded to 3 significant figures, which is done by using the 4th digit to round the 3rd: the 4th digit is 4, so the number rounds down to 9170
3.14159 to 5 decimal places. As the the 5th digit after the decimal place is a 9 when quoting to 4 decimal places the 4th digit is rounded up so Pi to 4 decimal places is: 3.1416 If you put it that way... 3.14159265358979323 So technically I am right but, If you round it up you get 3. Just little 3
Okay to the nearest 10000, means we look 4th number from the right. If it is less than 5 we round down, if greater or equal to we round up.244556 Therefore 240000
The rounded measurement will be 0.00310 m. The "9" in the 4th decimal place (0.0001) caused the "5" in the 5th decimal place to be rounded up.
Depends on what you need to round to for thousands it’s 1,000
