# truncateToDouble abstract method

double truncateToDouble()
override

Returns the integer double value obtained by discarding any fractional digits from `this`.

If this is already an integer valued double, including `-0.0`, or it is not a finite value, the value is returned unmodified.

For the purpose of rounding, `-0.0` is considered to be below `0.0`. A number `d` in the range `-1.0 < d < 0.0` will return `-0.0`, and in the range `0.0 < d < 1.0` it will return 0.0.

    print(2.5.truncateToDouble()); // 2.0
    print(2.00001.truncateToDouble()); // 2.0
    print(1.99999.truncateToDouble()); // 1.0
    print(0.5.truncateToDouble()); // 0.0
    print((-0.5).truncateToDouble()); // -0.0
    print((-1.5).truncateToDouble()); // -1.0
    print((-2.5).truncateToDouble()); // -2.0

## Implementation

    double truncateToDouble();
