Questions tagged [bigdecimal]

BigDecimal is a numeric object type in Java that represents decimal numbers with arbitrary precision.

Because double and float use a fixed amount of memory (64 and 32 bits respectively), they have limited precision which can lead to rounding errors, and more importantly, they cannot be used to represent all decimal fractions exactly as they use two's complement.

BigDecimal solves these problems by providing arbitrary precision and by using a decimal representation of their values.

The BigDecimal class also provides operations for arithmetic, scale manipulation, rounding, comparison, hashing, and format conversion.

More information can be found in the BigDecimal Javadoc
