Trying to change the amount of decimal points

This is what I have for the input function

weightArray=[68.6611,8.7929,71.6766,44.1901,76.2861,66.1515,22.6083,36.9491,52.6495,65.6995]
dailyMaterialSum = sum(weightArray,'All')

The output answer is correct, but I need it to only be at 2 decimal points. If I input fprintf('%10.2f \n', dailyMaterialSum) It produces the correct form of the answer, but it isn't considered correct because it's a seperate answer. Where am I supposed to place the fprintf to be correct?

These are the output equations

weightArray = (1 + (100 -1)*(rand (10,1)))'

dailyMaterialSum = MaterialSum(weightArray)

Probably the easiest is to use the round function:

weightArray=[68.6611,8.7929,71.6766,44.1901,76.2861,66.1515,22.6083,36.9491,52.6495,65.6995]

weightArray = 1×10

68.6611 8.7929 71.6766 44.1901 76.2861 66.1515 22.6083 36.9491 52.6495 65.6995

dailyMaterialSum = sum(weightArray,'All')

dailyMaterialSum = 513.6647

format short g
dailyMaterialSum = round(dailyMaterialSum, 2)

dailyMaterialSum = 
       513.66

format bank
dailyMaterialSum = round(dailyMaterialSum, 2)

dailyMaterialSum = 
        513.66

Also format to change the Command Window display.
