convertFrequency function

double convertFrequency(Frequency from, Frequency to, double value)

Convert frequencies. Some decimals may be lost in the proccess.

from, to and value can NOT be null, otherwise an AssertionError is thrown

Basic usage:

main() {
  final frequency = convertEnergy(
    Frequency.megahertz, // from
    Frequency.hertz, // to
    1, // value
  );
  print(frequency); // 1000000
}

Implementation

double convertFrequency(Frequency from, Frequency to, double value) {
  verify(from, to, value);
  if (from == to) return value;
  if (from == Frequency.hertz) {
    switch (to) {
      case Frequency.gigahertz:
        return value / 1e+9;
      case Frequency.kilohertz:
        return value / 1000;
      case Frequency.megahertz:
        return value / 1e+6;
      default:
        return value;
    }
  } else {
    final hertz = Frequency.hertz;
    switch (from) {
      case Frequency.gigahertz:
        return convertFrequency(hertz, to, value * 1e+9);
      case Frequency.kilohertz:
        return convertFrequency(hertz, to, value * 1000);
      case Frequency.megahertz:
        return convertFrequency(hertz, to, value * 1e+6);
      default:
        return value;
    }
  }
}
