  -== Type preserving accumulate functions
  -
  -In Drools 6 when using the ``sum`` function inside an accumulate pattern the result was always a Double regardless of the
  -field type on which the sum was performed. This caused the following 3 problems:
  -
  -* Loss of precision: the sum of a long `1881617265586265321L` will incorrectly return `1.88161726558626534E18`.
  -The BigDecimal sum of `0.09` and `0.01` will also be incorrect.
  -
  -* Loss of performance: summing with a Double total is significantly slower than summing with a Long or an Integer.
  -
  -* Leaked complexity: it enforced the user to pattern matching on Double, or more generically (suggested choice) on Number,
  -while it may be expected that the result of summing on a field of type Integer would be an Integer as well.
  -
  -Conversely Drools 7 preserves the type of the expression on which the sum is executed, so it will be possible to directly
  -match on that type as in:
