+ The `cir.complex.div` operation takes two complex numbers and returns
+ their division.
+
+ Range is used to select the implementation used when the operation
+ is lowered to the LLVM dialect. For division, 'improved' and
+ 'promoted' are all handled equivalently, producing the
+ Smith's algorithms for Complex division. If 'full' is used,
+ a runtime-library function is called if one of the intermediate
+ calculations produced a NaN value, and for 'basic' algebraic formula with
+ no special handling for NaN value will be used.
+
+ Example:
+
+ ```mlir
+ %2 = cir.complex.div %0, %1 range(basic) : !cir.complex<!cir.float>
+ %2 = cir.complex.div %0, %1 range(full) : !cir.complex<!cir.float>
