Detailed explanation-1: -To always round up (away from zero), use the ROUNDUP function. To always round down (toward zero), use the ROUNDDOWN function. To round a number to a specific multiple (for example, to round to the nearest 0.5), use the MROUND function.
Detailed explanation-2: -To round a number down to nearest 0.5, use the FLOOR function, for example =FLOOR(A2, 0.5) . To round a number up to nearest 0.5, use the CEILING function, for example =CEILING(A2, 0.5) . To round a number up or down to nearest 0.5, use the MROUND function, e.g. =MROUND(A2, 0.5) .
Detailed explanation-3: -If you wanted to use the number from cell A2 and have it rounded to two decimal places, you could enter =ROUND(A2, 2). Or, if you want to divide cell B2 by cell C2, and round the result to 3 decimals, you would use =ROUND(B2/C2, 3).
