Last Updated : 16 Oct, 2019

The java.math.BigDecimal.multiply(BigDecimal multiplicand) is an inbuilt method in java that returns a BigDecimal whose value is (this × multiplicand), and whose scale is (this.scale() + multiplicand.scale()). Syntax:
```
public BigDecimal multiply(BigDecimal multiplicand)
```
Parameters: This method accepts a single parameter multiplicand of BigDecimal type which refers to the Value to be multiplied by this BigDecimal. Return value: This method returns a BigDecimal whose value this * multiplicand. Below program illustrates the working of the above mentioned method: Program 1:
Output:
```
Multiplication is 769.640
```
Program 2:
Output:
```
Multiplication is -769.640
```
The java.math.BigDecimal.multiply(BigDecimal multiplicand, MathContext mc) is an inbuilt method in Java that returns a BigDecimal whose value is (this × multiplicand), with rounding according to the context settings. Syntax:
```
public BigDecimal multiply(BigDecimal multiplicand, MathContext mc)
```
Parameters: This method accepts two parameters:
- multiplicand - This is of BigDecimal type and refers to the value to be multiplied by this BigDecimal.
- mc - This refers to the context of rounding i.e., up to what decimal place the value is to be rounded off.
Return value: This method returns a BigDecimal whose value this * multiplicand, rounded as necessary. Program below demonstrates the method: Program 1:
Output:
```
Multiplication is 27.55
```
Program 2:
