IMLOG2(z)

This function gives the binary logarithm of a complex number.
$IMLOG2(z)$ , where $z$ is the complex number in the form of $x+iy$ . i.e. $x$ & $y$ are the real numbers.
$I$ imaginary unit . $i={\sqrt {-1}}$ .
Binary logarithm is the inverse function of Failed to parse (syntax error): {\displaystyle n ↦ 2n} .
Log base 2 is called Binary logarithm.
To find the Binary logarithm of a complex number we have to calculate from the natural logarithm.
So $log2(x+iy)=(log_{2}e)ln(x+iy)$ .
We can use COMPLEX function to convert real and imaginary number in to a complex number.

-#=IMLOG2("0")=NULL
+#=IMLOG2("0") = NULL
-*Imln("8") for that it should consider the imaginary value is zero,but calci is not considering like EXCEL
