Purpose
Convert coefficients to complex number
Return value
Complex number as text
Arguments
- real_num - The real number.
- i_num - The imaginary number.
- suffix - [optional] The suffix, either "i" or "j".
Syntax
=COMPLEX(real_num, i_num, [suffix])
Usage notes
A complex number has two parts: a real number and an imaginary number. The COMPLEX function converts real and imaginary coefficients into a complex number of the form x + yi or x + yj, where x represents the real number and y represents the imaginary number. For example:
=COMPLEX(5,3) // returns 5+3i
To use the "j" instead of "i":
=COMPLEX(5,3,"j") // returns 5+3j
In the example shown, the formula in E6 is:
=COMPLEX(B6,C6)
Notes:
- If omitted, suffix defaults to "i".
- suffix must be lowercase "i" or "j"; other values result in a #VALUE error.
- If real_num or i_num are nonnumeric, COMPLEX returns the #VALUE! error.
