最大浮线宽度

Question

In go, the statement

fmt.Sprintf("%4.3f", 18.8836)

Will return

18.883

Is there a way of making the return value

18.88

In other words, is there a way to make the 4 apply to the whole width of the number and not just the decimal portion?

Answer 1

You can accomplish this with %g:

fmt.Printf("%.4g
", 18.8836)
