Formula Field Showing Incorrect Value

Hi there, not sure if its a bug or a setting I’ve missed but I have a formula field that seems to be rounding down when its not set to.

If you see the below, Noloco totals £627.76 but a manual calculator totals it as £627.78. Exporting to Excel also reports it incorrectly which I think is down to some values being reported as £16.42 but underneath its £16.416

Excel showing this

Fixed this by using ROUND(FIELD1*FIELD2/100,2)
