The IMSQRT
function computes the square root of a complex number.
Parts of a IMSQRT function
The IMSQRT
formula is formatted as =IMSQRT(complex_number).
| Part | Description | Notes |
| complex_number | The complex number to take the square root of. |
Sample formulas
IMSQRT(2)
IMSQRT("3+2i")
Notes
- This function is equivalent to using
IMPOWER(complex_number, 0.5). - While it is not possible to use the
SQRTfunction to take the square root of a negative real number, it is possible to useIMSQRTto take the square root of a complex number with a negative real number component.
