There are Round and RoundToEven which do exactly what you say unless I am missing something.

Please update your proposal clarifying what is missing in those functions that you require otherwise. Thanks.

Would the following exhibit the behavior you want?

func RoundOut(x float64) float64 {
	return math.Copysign(math.Ceil(math.Abs(x)), x)
}

Note that your proposed behavior is "round away from zero", which is non-standard. I'm not exactly sure why one would want to round -1.3 down to -2.0 as well as 1.3 to 2.0. Can you please explain your use case?

Go implements the IEEE rounding modes (API: Ceil, Floor, Trunc, Round, RoundToEven - #21748). Other discussions in #20100, #4594.

I'm not sure there would be much demand for esoteric non-IEEE modes in the standard library.

Sorry I missed that this is about rounding also 1.3 to 2 apart from 1.7 to 2. In any case, the question still stands to explain the use case for this and why does this need to be in the standard library.

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
