This is a follow-up on 126. BigDecimal addition

In this problem, you are asked to **implement the multiplication of two decimals with arbitrary digits**.

```
multiply(
'1123456787654323456789',
'1234567887654323456'
)
// '1386983673205309924427166592431045142784'
multiply(
'-1123456787654323456789',
'1234567887654323456.12348'
)
// '-1386983673205309924565891036570601003228.30572'
multiply(
'-0.12345',
'-1.6789012'
)
// '0.20726035314'
```

- This problem covers 114. implement BigInt multiplication.
- trailing zeroes in the result should be removed.
- Big.js defaults return exponential notation when it is too big, in this problem,
**don't do that**
