operator - method
Subtract two complex number
Examples
var c1 = Complex(real: 1, imaginary: 1);
var c2 = Complex(real: 1, imaginary: 1);
print(c1 - c2);
/* output:
Complex(real: 0.0, imaginary: 0.0)
*/
Implementation
Complex operator -(Complex b) {
return Complex(real: real - b.real, imaginary: imaginary - b.imaginary);
}
