C questions should go to comp.lang.c (INFO-C).

Try (*(union{int i;float f;})integer).f
which should work but probably will give your compiler indigestion.

If that doesn't work, store it into such a union's integer member
then extract the float member of the union:
	union {int i; float f} u;
	u.i = integer;
	expression( u.f );
