cc.v2的floor接口被取消了？

Creator 2.x
#1

  • Creator 版本：2.3.4

  • 重现方式：cc.v2(1.23, 1.3).floor()
    直接报错说：floor不是一个function

#2

貌似这么玩了：
this.text = cc.Vec2.floor(cc.v2(),cc.v2(6.99,8.66));
this.label.string = this.text;
this.text = cc.Vec2.floor(cc.v3(),cc.v3(6.99,8.66,6.99));
this.label.string = this.label.string+"\n"+this.text;
this.text = cc.Vec3.floor(cc.v3(),cc.v3(6.99,8.66,6.99));
this.label.string = this.label.string+"\n"+this.text;
