BigDecimal

java.math.BigDecimal provides for immutable arbitrary-precision signed decimal numbers. A BigDecimal consists of an arbitrary precision integer unscaled value (a BigInteger 2’s complement variable length array of bytes) and a non-negative 32-bit integer scale, which represents the number of digits to the right of the decimal point. That allows you to work with decimal fractions of arbitrary precision.
