IMSQRT functionThe IMSQRT function computes the square root of a complex number.
Parts of a IMSQRT function
The IMSQRT formula is formatted as =IMSQRT(complex_number).
The complex number to take the square root of.
This function is equivalent to using IMPOWER(complex_number, 0.5).
While it is not possible to use the SQRT function to take the square root of a negative real number, it is possible to use IMSQRT to take the square root of a complex number with a negative real number component.
IMPOWER: The IMPOWER function returns a complex number raised to a power.
COMPLEX: The COMPLEX function creates a complex number, given real and imaginary coefficients.
