/// # Purpose {#bslstl_complex-purpose}
/// Provide functionality of the corresponding C++ Standard header.
///
/// **Canonical header:**  bsl_complex.h
///
/// # Description {#bslstl_complex-description}
/// This component is for internal use only. Please include
///`<bsl_complex.h>` directly.  This component imports symbols declared in the
/// <complex> header file implemented in the standard library provided by the
/// compiler vendor.
///
/// ## User-defined literals {#bslstl_complex-user-defined-literals}
///
///
/// This component provides a set of user-defined literals (UDL) to form
/// `bsl::complex` objects with various ranges of values.  The ud-suffixes are
/// preceded with the `_` symbol to distinguish between the `bsl`-complex's UDLs
/// and the `std`-complex's UDLs introduced in the C++14 standard and
/// implemented in the standard library.  Note that `bsl`-complex's UDLs, unlike
/// the `std`-complex's UDLs, can be used in a client's code if the current
/// compiler supports the C++11 standard.
///
/// Also note that `bsl`-complex's UDL operators are declared in the
/// `bsl::literals::complex_literals` namespace, where `literals` and
/// @ref complex_literals  are inline namespaces.  Access to these operators can be
/// gained with either `using namespace bsl::literals`,
/// `using namespace bsl::complex_literals` or
/// `using namespace bsl::literals::complex_literals`.  But we recommend
/// `using namespace bsl::complex_literals` to minimize the scope of the using
/// declaration.
///
/// ## Usage {#bslstl_complex-usage}
///
///
/// In this section we show intended use of this component.
///
/// ### Example 1: Basic bsl-complex's UDLs Usage {#bslstl_complex-example-1-basic-bsl-complex-s-udls-usage}
///
///
/// This example demonstrates basic use of the complex user-defined literal
/// operators.
///
/// First, we provide an access to `bsl`-complex's UDLs.
/// @code
/// using namespace bsl::complex_literals;
/// @endcode
/// Then, we construct a `bsl::complex` object `z`.
/// @code
/// auto z = 1.0 + 1_i;
/// @endcode
/// Finally, stream the magnitude of the complex number `z` to `stdout`:
/// @code
/// printf("abs(%.1f,%.1f) = %f\n", z.real(), z.imag(), bsl::abs(z));
/// @endcode
/// The streaming operator produces output in the following format on `stdout`:
/// @code
/// abs(1.0,1.0) = 1.414214
/// @endcode
