It is widely used in network services, cloud computing and other fields. When developing in the Go language, you sometimes encounter some unexpected results. This may be caused by code logic problems, data processing errors, or some special circumstances. Understanding the characteristics and common problems of the Go language can help developers better solve and debug programs and improve development efficiency. In the following articles, we will answer some common questions and share some solutions and tips.

Question content

I am making a program to calculate the percentage of males and females in a class. But it gives me an incorrect result.

The code is:

package main
import {
    "fmt"
}

var total, mujeres, hombres float64

func main() {
    fmt.printf("número de mujeres:")
    fmt.scanln(&mujeres)

    fmt.printf("número de hombres:")
    fmt.scanln(&hombres)

    total = mujeres + hombres
    mujeres = (mujeres / total) * 100
    hombres = (hombres / total) * 100

    print("en al salón de clases hay ", mujeres, "% de mujeres y ", 
        hombres, "% de hombres")
}

The output obtained when inputting two quantities of 50 is:

En al salón de clases hay +5.000000+001% de mujeres y +5.000000+001% de hombres

I would like to know what causes this problem and how to solve it.

Workaround

Instead of giving the wrong result, it gives the correct result in the wrong format. Value 5.000000e 001 is 5x10<sup>1</sup>, which is equal to 50.

If you want them to be in a different format than the default, you need to specify, for example:

fmt.Printf("En al salón de clases hay %.1f%% du mujeres y %.1f%% du hombres\n",
    mujeres, hombres)
