isClose method

@override bool isClose(Complex<num, num> other, { double relTol = 1e-09, double absTotal = 0.0, })

Return true if the values Complex and other are close to each other and false otherwise. Whether or not two values are considered close is determined according to given absolute and relative tolerances. relTol is the relative tolerance – it is the maximum allowed difference between Complex and other, relative to the larger absolute value of Complex and other. For example, to set a tolerance of 5%, pass relTol:0.05. The default tolerance is 1e-09, which assures that the two values are the same within about 9 decimal digits. relTol must be greater than zero absTotal is the minimum absolute tolerance – useful for comparisons near zero absTotal must be at least zero.

Implementation

@override
bool isClose(Complex other, {double relTol = 1e-09, double absTotal = 0.0}) {
  return abs(this - other) <=
      math.max(relTol * math.max(abs(this), abs(other)), absTotal);
}
