You can't round on a calculator. You do it in your head. 4-1, you round down, 5-9, you round up.
1/3 = 1 ÷ 3 = 0.333... (with the 3 recurring). When rounding to any number of decimal places it will round down, so stop after as many 3s as decimal places to which you want to round. eg to 1 dp 1/3 ≈ 0.3 to 4 dp 1/3 ≈ 0.3333
The second decimal place is the 9. It is followed by a 1, which is less than 5, so we round it down to 1.39.
To round up 0.45 to 2 decimal places, you need to look at the third decimal place, which is 5 in this case. Since 5 is equal to or greater than 5, you round up the last digit in the second decimal place by adding 1. Therefore, 0.45 rounded to 2 decimal places would be 0.46.

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)
