How to change symbolic values to numbers


Hello for all.
I have a problem with changeing symbolic to number values:

f1[{x1_,x2_}]=Block[{},
	L={x1, 1-x1};

Print[L]; (*Print prints  {x1, 1-x1} but I want to get value {.5, .
5)*)

];

fCE=f1[{x1,x2}]; fC[{x1_, x2_}]=fCE;
fCi:=(N[f1[#]])&;
fCa=fCi[{.5,.5}];
fCa

Any help would by very appreciated.
With best regards,
Krzysztof Lisowski
