toRealArray method
Returns the real components of the Float64x2List.
This method just discards the imaginary components. It doesn't check whether the imaginary components are actually close to zero.
Implementation
Float64List toRealArray() {
final r = Float64List(length);
for (int i = 0; i < r.length; ++i) {
r[i] = this[i].x;
}
return r;
}
