Constants for One, Ten and Zero

BigDecimal class is an immutable class and represents a signed decimal number of arbitrary precision with an associated scale. BigDecimal declares three convenience constants: ONE, TEN, and ZERO. Each constant is the BigDecimal equivalent of 1, 10, and 0 with a zero scale.

static BigDecimal ONE The value 1, with a scale of 0.
static BigDecimal TEN The value 10, with a scale of 0.
static BigDecimal ZERO The value 0, with a scale of 0.

BigDecimal(0.1) results in 0.100000000000000005 being stored in the instance. BigDecimal("0.1") stores 0.1 exactly.

Value of 1, 10, and 0 in BigDecimal

static BigDecimal ONE The value 1, with a scale of 0.
static BigDecimal TEN The value 10, with a scale of 0.
static BigDecimal ZERO The value 0, with a scale of 0.
