JAVA : Divide 2 bigdecimals and retain maximum number of digits after the decimal point

I want to divide 2 big decimals and retain maximum possible number of digits(say 1000 digits) in the non-terminating division result. What code shall I write to do this ?

Please note : Is it possible to have a high accuracy implementation as I am dealing with important data .

Solution

  • Use an overloaded divide method of BigDecimal that takes a scale as an argument; you can get an arbitary scale that way.

    divide(BigDecimal divisor, int scale, RoundingMode roundingMode)
