Use BigDecimal, int, or long for monetary calculations instead of float and double types

Advantages of using BigDecimal

• You want to have full control over rounding
• You don’t mind keeping track of the decimal point
• You don’t mind the inconvenience and cost of not using a primitive type

Disadvantages to using BigDecimal

• Less convenient than using a primitive arithmetic type
• A lot slower

An alternative to using BigDecimal is to use “int” or “long”, if you wan’t to keep track of the decimal point yourself

• If the quantities don’t exceed nine decimal digits, use int
• If the quantities exceed eighteen digits, use long
• If the quantities might exceed eighteen digits, use BigDecimal
