• Last Updated : 08 Jan, 2020

BigDecimal#*() : *() is a BigDecimal class method which return multiplicative value of two BigDecimal values.

```Syntax:  BigDecimal.*()

Parameter:  BigDecimal values - two operands

Return:  Mulitplicative value of BigDecimal values
```

Code #1 : Example for *() method

 `# Ruby code for BigDecimal.*() method``   ` `# loading BigDecimal``require ``'bigdecimal'``   ` `# declaring BigDecimal``a = ``42``.``1``**``13``   ` `# declaring BigDecimal``b = -BigDecimal(``"10"``)``   ` `# declaring BigDecimal``c = -(``22` `* ``7``.``1``) ** ``10`` ` `# multiplicative value``puts ``"BigDecimal a * b : #{a*b}\n\n"`` ` `# multiplicative value``puts ``"BigDecimal b * c : #{b*c}\n\n"`` ` `# multiplicative value``puts ``"BigDecimal a * c : #{c*a}\n\n"`

Output :

```BigDecimal a * b : -0.1305170490200644E23

BigDecimal b * c : 0.8645901738210328E23

BigDecimal a * c : -1.1284375809886571e+43
```

Code #2 : Example for *() method

 `# Ruby code for BigDecimal.*() method``   ` `# loading BigDecimal``require ``'bigdecimal'``   ` `# declaring BigDecimal``a = ``12``**``12` `- ``27``   ` `# declaring BigDecimal``b = BigDecimal(``'10'``)-(``22` `* ``7``.``1``) ** ``10``   ` `# declaring BigDecimal``c = BigDecimal(``'-3'``)`` ` `# multiplicative value``puts ``"BigDecimal a * b : #{a*b}\n\n"`` ` `# multiplicative value``puts ``"BigDecimal b * c : #{b*c}\n\n"`` ` `# multiplicative value``puts ``"BigDecimal a * c : #{c*a}\n\n"`

Output :

```BigDecimal a * b : -0.7708772836340099569698794810751771E35

BigDecimal b * c : 0.2593770521463098399997E23

BigDecimal a * c : -0.26748301344687E14
