    Checks if each double in a sequence is arbitrarily close to 0.0 and if so, converts it to 0.0.

    Checks if each double in a sequence is arbitrarily close to 0.0 and if so, converts it to 0.0.

    values

    A sequence of double values.

    returns

    A new sequence of doubles where any element in the original sequence that is within ESPILON of 0.0 is converted to 0.0. All other elements of the sequence are unchanged.

  6. def applyTolerance(d: Double): Double

    Permalink

    Converts a value to 0.0 if it is arbitrarily close to it.

    Converts a value to 0.0 if it is arbitrarily close to it.

    d

    A double value.

    returns

    If the value is within EPSILON of 0.0, then 0.0. Otherwise, the value is returned unchanged.
