Constructor
new BigDecimal(unscaledValue, scale)
Constructs an immutable arbitrary-precision signed decimal number.
A BigDecimal consists of an arbitrary precision integer
unscaled value and a 32-bit integer scale. If zero
or positive, the scale is the number of digits to the right of the
decimal point. If negative, the unscaled value of the number is
multiplied by ten to the power of the negation of the scale. The
value of the number represented by the BigDecimal is
therefore (unscaledValue × 10-scale).
Parameters:
| Name | Type | Description |
|---|---|---|
unscaledValue |
Integer | Number | The integer part of the decimal. |
scale |
Number | The scale of the decimal. |
