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).

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 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.

Examples

	A	B
1	Formula	Result
2	=IMSQRT(4)	2
3	=IMSQRT("3+4i")	2+i
4	=IMSQRT("3-4j")	2-j
5	=IMSQRT(COMPLEX(3, 4))	2+i
