Rounding bigdecimal to always have two decimal places

Question

Below is my code implementation to round BigDecimal values to two decimal places: 

BigDecimal rounded = value.round(new MathContext(2, RoundingMode.CEILING));

logger.trace("rounded {} to {}", value, rounded);

This is the respective output: 

rounded 0.819 to 0.82

rounded 1.092 to 1.1

rounded 1.365 to 1.4 // should be 1.37

rounded 2.730 to 2.8 // should be 2.74

rounded 0.819 to 0.82

The problem is it doesn’t round all the values. Can anyone tell me how to do this with BigDecimal or with another class/library? 

Answer 1

You can use RoundingMode to round the decimal value. 

my_value = my_value.setScale(2, RoundingMode.CEILING)
