IMSQRT (ComplexNumber)

${\sqrt {z}}={\sqrt {x+iy}}={\sqrt {r.e^{i\theta }}}={\sqrt {{r}(cos({\frac {\theta }{2}})+isin({\frac {\theta }{2}})}}$

where $r$ is the modulus of $z$ . $r={\sqrt {x^{2}+y^{2}}}$
And $\theta$ is the argument of $z$ . $\theta =tan^{-1}(y/x)$ also $\theta \in (-\pi ,\pi ]$ .
We can use COMPLEX function to convert real and imaginary number in to a complex number.

The syntax is to calculate square root of a complex number in ZOS is .
- $ComplexNumber$ is of the form $z=x+iy$
For e.g.,IMSQRT("9+10i")
IMSQRT(IMSUB("9+10i","-2-3i"))
