Syntax: cexpand(expression,var)
Examples (please note that i=sqrt(-1)):
* expand((x-i)^3,x) => x*(x^2-3)+(1-3*x^2)*i [Not completely expanded]
cexpand((x-i)^3,x) => i+x^3-3i*x^2-3x
* cexpand((x-5)*(x-5)*(x-(1-i))*(x+(1-i)),x) => 50i+(2i+25)*x^2+x^4-10x^3-20i*x
Unfortunately, no more releases of this function will be made :(
