IMSQRT (ComplexNumber)
- is of the form .
- IMSQRT(),returns the difference between two complex numbers
is of the form 
.
Description
- This function gives square root of a complex number.
- IMSQRT(ComplexNumber), where complex number is in the form of "x+iy".
- where x&y are the real numbers. imaginary unit ..
- Consider the complex number z.
- The square root of a complex number is defined by:
imaginary unit .
.
- where is the modulus of .
- And is the argument of . also .
- We can use COMPLEX function to convert real and imaginary number in to a complex number.
is the modulus of 
. 
is the argument of

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