ok I apparently was using 1.x compiler (I've downloaded what was linked from 
main page).
Now when I have downloaded newest version (2.005) I get the following error 
with both methods (toFloat and to!):

test.d(10): Error: cannot implicitly convert expression (toString(fFloat)) 
of ty
pe const(char)[] to char[]

same code, nothing changed, same error on both method of conversion.
