Press MATH, choose NUM at the top, then choose round(. Type 0.9528, then a comma, then the number of digits you want to round to. For example, to round to three decimal places, type: round(0.9528,3)
Round up to the greater thousand if:the last three digits of the number are greater than 500, orthe last three digits of the number are 500 and the greater thousand is even.Round down to the smaller thousand if:the last three digits of the number are less than 500, orthe last three digits of the number are 500 and the lesser thousand is even.Many schools teach that 500 should always be rounded up. This is a simpler rule but is wrong since such rounding introduces a bias in the results.
