Met en uvre les oprateurs binaires pour l'arithmtique complexe et mixte complexe / scalaire arithmtique. Arguments scalaires sont traites comme des nombres complexes avec la partie relle gale l'argument et la partie imaginaire zro .
Original:
Implements the binary operators for complex arithmetic and for mixed complex/scalar arithmetic. Scalar arguments are treated as complex numbers with the real part equal to the argument and the imaginary part set to zero.
