IMSQRT function

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




  • 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.
