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

If this function is not available, and returns the #NAME? error, install and load the Analysis ToolPak add-in.

Syntax

COMPLEX(real_num,i_num,suffix)

Real_num   is the real coefficient of the complex number.

I_num   is the imaginary coefficient of the complex number.

Suffix   is 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.
