Why does the go language have no min/max (int, int) function

Golang why there is no Min/max (int, int) function

We know that the Go language math package defines the Min/max function, but it is of the float64 type and does not have an integer type of Min/max.

The Min/max function defined in the Go language math package is as follows:

math.Min(float64, float64) float64math.Max(float64, float64) float64

In fact, we are more often compared to a two-integer scenario:

math.Min/Max(int, int), ormath.Min/Max(int64, int64)

So why does the go language not provide the integer type of Min/max these two functions? The following article gives an explanation:

To sum up, the main reason is that

1. Since the float64 type handles infinity and Not-a-number, and their processing is complex and the average user is not capable, all go needs to provide a system-level solution to the user.
2. For int/int64 types of data, the implementation of Min/max is straightforward, and the user can fully implement it himself, for example:

func Min(x, y int64) int64 {    if x < y {        return x    }    return y}

The conclusion is that go wants users to implement such simple functions themselves.

So my question is:
Because the use of Min/max (int, int) is so common, does it require users to implement a Min/max code within each of their own projects, and why not put them in the system library such as math, for everyone to use?
