*inumber1*- Complex number 1.*inumber2*- [optional] Complex number 2.

## How to use

The Excel IMPRODUCT function returns the product of one or more complex numbers. Complex numbers are input as text, and must be in the form x + yi or x + yj. The result of IMPRODUCT is a complex number as text.

For example:

```
=IMPRODUCT("1+2i",3) // returns "3+6i"
=IMPRODUCT("1+2i","1+2i") // returns "-3+4i"
```

In the example shown, the formula in D6, copied down, is:

```
=IMPRODUCT(B6,C6)
```

Notes:

- Only lowercase "j" and "i" are accepted by IMPRODUCT. Other values will result in the #NUM error.
- IMPRODUCT can handle up to 255 numbers
