# round abstract method

int round()
override

Returns the integer closest to this number.

Rounds away from zero when there is no closest integer: `(3.5).round() == 4` and `(-3.5).round() == -4`.

Throws an UnsupportedError if this number is not finite (NaN or an infinity).

    print(3.0.round()); // 3
    print(3.25.round()); // 3
    print(3.5.round()); // 4
    print(3.75.round()); // 4
    print((-3.5).round()); // -4

## Implementation

    int round();
