real_num |
Number | Required | The real coefficient of the complex number. |
i_num |
Number | Required | The imaginary coefficient of the complex number. |
suffix |
Text | Optional | The suffix for the imaginary component of the complex number. If omitted, suffix is assumed to be "i". |
▣ Examples
Complex number with 3 and 4 as the real and imaginary coefficients
=COMPLEX(3,4)
Result:
3+4i
Complex number with 3 and 4 as the real and imaginary coefficients, and j as the suffix
=COMPLEX(3,4,"j")
Result:
3+4j
Complex number with 0 and 1 as the real and imaginary coefficients
=COMPLEX(0,1)
Result:
i
Complex number with 1 and 0 as the real and imaginary coefficients
=COMPLEX(1,0)
Result:
1
§ 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.
⚠ Common Errors
#VALUE!
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.
