round method

int round()

Returns the integer closest to this number.

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

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

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

Implementation

int round() => value.round();
