    • parseToMinimalNumericType

      public static Number parseToMinimalNumericType(String numStr)
      Parse the passed in String as a numeric value and return the minimal data type between Long, Double, BigDecimal, or BigInteger. Useful for processing values from JSON files.
      Parameters:
      numStr - String to parse.
      Returns:
      Long, BigInteger, Double, or BigDecimal depending on the value. If the value is and integer and between the range of Long min/max, a Long is returned. If the value is an integer and outside this range, a BigInteger is returned. If the value is a decimal but within the confines of a Double, then a Double is returned, otherwise a BigDecimal is returned.
