# COMPLEX

### Description

Converts real and imaginary coefficients into a complex number of the form x + yi or x + yj.

### Sample Usage

### Syntax

COMPLEX(real_num, i_num, [suffix])

The COMPLEX function syntax has the following arguments:

Real_num Required. The real coefficient of the complex number.

I_num Required. The imaginary coefficient of the complex number.

Suffix Optional. The suffix for the imaginary component of the complex number. If omitted, suffix is assumed to be "i".

NOTE: All complex number functions accept "i" and "j" for suffix, but neither "I" nor "J". Using uppercase results in the #VALUE! error value. All functions that accept two or more complex numbers require that all suffixes match.

### Remarks

If real_num is nonnumeric, COMPLEX returns the #VALUE! error value.

If i_num is nonnumeric, COMPLEX returns the #VALUE! error value.

If suffix is neither "i" nor "j", COMPLEX returns the #VALUE! error value.
