BigDecimal constants
In this chapter you will learn:
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 ONEThe value 1, with a scale of 0.static BigDecimal TENThe value 10, with a scale of 0.static BigDecimal ZEROThe 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 ONEThe value 1, with a scale of 0.static BigDecimal TENThe value 10, with a scale of 0.static BigDecimal ZEROThe value 0, with a scale of 0.
