- // Definitions for complex number support. The ANSI C++ proposal
- // specifies a templated class for this, e.g. complex<double> or
- // complex<float>, but not all compilers currently support this. TNT
- // provides a mechanism to accomodate any complex number class,
- // using "DComplex" and "FComplex" names for double-precision
- // and single-precision instances, respectively. For example,
- // if your system uses the older "Complex" number class, compile as
- //
- // CC -DTNT_DCOMPLEX_TYPE='Complex'
- //
- // Now DComplex
