There are different guidelines depending on the arithmetic operation being used.
That would depend on what you were rounding it to. If rounding to the nearest whole number, then it does not need rounding. If rounding to the nearest ten, it would be 420. If rounding to the nearest hundred, it would be 400.
Rounding factors can lead to underestimates or overestimates: the outcome depends on the rounding.
The depends to what decimal place you are rounding the number.If you are rounding to hundredths, it will be 2.27If you are rounding to tenths, it will be 2.3If you are rounding to the nearest whole number, it will be 2.
It depends what you are rounding to. If rounding to the nearest whole number, it would be 41. If rounding to the nearest tenth, it would not change. If you were rounding to the nearest ten, it would be 40.

18 is an integer, so no rounding is necessary. You can indicate the precision of the number, if you wish, using zeroes: 18.00.
1.2
The precision of a number is determined by its last digit. The true value lies with a half of the place value of this last digit. In the above case it is the 6, which is in the thousandths place. So the true value lies within half-of-one-thousandths of the given number. That is, it lies in the interval [234.8955, 234.8965]. I use round-to-even, which is the default rounding mode used in IEEE 754 standard for computing functions and operators.
Three. On the grounds that the zero after the decimal point is an indicator of precision (rounding) rather than simply a [redundant] place holder.
The rounded off number of 1.875 depends on the level of precision required. If rounding to the nearest whole number, the rounded off number of 1.875 is 2. If rounding to the nearest tenth, the rounded off number is 1.9.
186 is an integer, so it needs no rounding. It has no parts smaller than 0.01. To indicate the precision of the number, you can write 186.00.
In engineering, the precision of a quantity is implicitly told in the number of digits presented. In the number 254.34, the precision is of six digits. If by one hundredth it is meant 1/100 of the unit then the number in question is already given to the nearest hundredth. No more rounding is necessary. If the rounding is going to be down to the nearest hundred, then the number is written as 3 x 10^2. This means the quantity has dropped down to a one order magnitude level. Precision of the number is just of one digit. RafaelRZ :The answer provided by' Ericbames' is correct.
After allowing for rounding, measurement errors etc, let me see ... Yes, there are exactly 118 hectometres in 118 hectometres.
