**subtract**(

**BigDecimal**subtrahend, MathContext mc) returns a

**BigDecimal**whose value is (this - subtrahend), with rounding according to the context settings. If subtrahend is zero then this, rounded if necessary, is used as the result. If this is zero then the result is subtrahend. negate(mc).

Also know, how do I use BigDecimal?

**Using a BigDecimal implies that you should:**

- Create new BigDecimal variables, using the constructor.
- In order to add a BigDecimal to another BigDecimal, use add(BigDecimal augend) API method, that returns a BigDecimal whose value is (this + augend), and whose scale is max(this.

**BigDecimal**.

**divide**(

**BigDecimal**divisor, int scale, RoundingMode roundingMode) returns a

**BigDecimal**whose value is (this / divisor), and whose scale is as specified. If rounding must be performed to generate a result with the specified scale, the specified rounding mode is applied.

Similarly, it is asked, can BigDecimal be negative?

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.

They are very **different**. Besides the **difference** in precision, the most important **difference** is that **BigDecimal** is a specifically decimal type. That means it's designed to represent fractions with finite-length decimal (base-10) representations. On the other hand, **double** is a base-2 floating-point number.
