+====== Complex ======
+###
+boolean, read-only.
+###
+###
+For an operator //O//, //O.Complex// returns a boolean (//true// or //false//) stating if the operator contains complex numbers or not.
+###
+===== Example =====
+###
+We define:
+$$O=3.4+1.2a^{\dagger}_{0}\,a^{\phantom{\dagger}}_{0}+(2.5+I)a^{\dagger}_{1}\,a^{\phantom{\dagger}}_{2},$$
+and
+$$O=3.4+1.2a^{\dagger}_{0}\,a^{\phantom{\dagger}}_{0}+(2.5)a^{\dagger}_{1}\,a^{\phantom{\dagger}}_{2},$$
+and print for each of these operators if they are complex or not. (true for the first case, false for the second case).
+###
+==== Input ====
+<code Quanty Example.Quanty>
+NF=3
+NB=0
+O = NewOperator(NF,NB,{{3.4},{0,-0,1.2},{1,-2,2.5+I}})
+print(O.Complex)
+O = NewOperator(NF,NB,{{3.4},{0,-0,1.2},{1,-2,2.5}})
+print(O.Complex)
