Imaginary Part
The imaginary part ![I[z]](http://mathworld.wolfram.com/images/equations/ImaginaryPart/Inline1.gif)
of a complex number 
is the real number multiplying i, so ![I[x+iy]=y](http://mathworld.wolfram.com/images/equations/ImaginaryPart/Inline3.gif)
. In terms of 
itself,
where 
is the complex conjugate of 
. The imaginary part is implemented in the Wolfram Language as Im[z].
