In Excel, the second argument of the Round function specifies the number of decimal places to round to. If this number is negative, it rounds to corresponding digits before the decimal point.
2 decimal places is the second number after the decimal point. So in 13.256 the 5 is the second decimal place. To round, you look at the number to the right of the decimal place you want to round to. So in 13.256 we look at the 6. If a number is greater than or equal to 5 you round up, if the number is less than 5 you round down. So 13.256 rounded to 2 decimal places is 13.26%
The number 6.527314 to two decimal places is 6.53. To round a number to two decimal places, you look at the third decimal place. If it is 5 or greater, you round up the second decimal place. If it is less than 5, you leave the second decimal place as is. In this case, the third decimal place is 7, so we round up the second decimal place from 2 to 3.
217.7 a tenth is the first number after the decimal place. If the second number after the decimal place is 5 or more than you round up (i.e. from 7 to), but in this case the second number is less than 5 so you round down to .7
As I would explain and show students, in order to round, you look at the number in the place to the right of where you want to round. If that number is 5 or more, you round up. If it's less than 5, you round down.For example, you want to round 12.54 to 1 decimal place. Look at the number in the second decimal place. That number is a 4, which is less than 5. So you'd round this down. That means your answer would be 12.5.But what if the original number was 12.58 and you needed to round this to 1 decimal place. The number in the second decimal place is an 8, which is greater than 5. So you'd round up. That means taking the number in the first decimal place and increasing it by one. So you'd round to 12.6.
Press MODE. The second line will say FLOAT and then have the numbers 1-9. If FLOAT is selected, the calculator will not round. If a number is selected, the calculator will round to that number of decimal places. For example, if you wanted to round everything to 3 decimal places, you would select "3". You can also use the round command. To get to it, press MATH, select NUM and the top and choose the second option, "round(". Type the number and then the decimal place you want to round to, separated by a comma. For example, if you wanted to round 2.569 to 2 decimal places, you would type round(2.569,2)
The '9' is in the "first decimal" place and the '3' is in the "second decimal" place.Rules for roundingIf the number in the second decimal place is 5 or greater then the number in the first decimal place is rounded upwards by 1.If the number in the second decimal place is 4 or less then the number in the first decimal place is left unchanged.As the problem in this case is 3.93 and the number in the second decimal place is less than 5, we end up with3.9 "correct to one decimal place" or "rounded to one decimal place".
To round 13.681 to once decimal place, you first need to look at the second decimal place and determine it's value. If the number is less than five, you will keep the number that is in the first decimal place. In this case, the number in the hundredths (second) position is an eight, which is greater than five. Therefore, we must change the six to a seven. The answer would be: 13.7
If the second number after the decimal (hundredths) is less than 5 it rounds to the first number after the decimal (tenths). If the second number after the decimal (hundredths) is 5 or greater it rounds to one higher than the first number after the decimal (tenths). For example 0.14 = .1 0.16 = .2
Oh, what a happy little question! To round 3.07 to one decimal place, we look at the second decimal digit, which is 7. Since 7 is 5 or greater, we round the number up to 3.1. There you go, a perfectly rounded number to brighten your day!
125.4 Taking a look at the number 125.3546 and wanting to round to the 1st decimal place you would take a look at the second decimal number (5) and see that it is greater than 5 so the 3 on 125.3 would round up to 4 to get the answer of 125.4
Look at the number in the second decimal place. If that number is 4 or less, zero it and everything to the right of it out. If that number is 5 or higher, increase the first decimal place by one and zero everything to the right of it out.
