java.bigDecimal divide in ruby environment

Question

I right script in Ruby that include java classes

require 'java'
include_class 'java.math.BigDecimal'
include_class 'java.math.RoundingMode'

during the script I need to divide 2 java.bigDecimal

 one = BigDecimal.new("1")
 number1 = BigDecimal.new("3")
 number1 = one.divide(number1,RoundingMode.new(HALF_EVEN))

since I don't have intellisense in this IDE I'm not sure the syntax is right and the runtime error is:

uninitialized constant::HALF_EVEN

1. do I combine java object in the ruby scrpit in the right way?
2. how should I divide two java.bigDecimal object in ruby env?

Answer 1

Try

number1 = one.divide(number1, RoundingMode::Half_EVEN)
