- % This is COMPLEX.TEX as of 2-MAR-1990
- %
- % Purpose: German math publications use double-line symbols for number sets
- % (real, comlex, ... numbers) that are not included in standard-TeX
- %
- % Here are some quick hacks from the Institute of Applied Mathematics,
- % University of Bonn, West Germany, for solving this problem without using
- % special fonts.
- %
- % Usage:
- % \rz for real numbers symbol ( Reelle Zahlen )
- % \nz for natural numbers symbol ( Nat"urliche Zahlen )
- % \gz for integer numbers symbol ( Ganze Zahlen )
- % \cz for complex numbers symbol ( Komplexe Zahlen )
- % \qz for rationale numbers symbol ( Rationale Zahlen )
