funcAtoi(sstring)(iint, errerror) AI代码助手复制代码 如果传入的字符串参数无法转换为int类型,就会返回错误。 packagemainimport"fmt"import"strconv"funcmain(){ s1 :="100"i, err := strconv.Atoi(s1)iferr !=nil{ fmt.Println("can't convert to int") }else{ fmt.Printf("type:%T value:%#...
strconv.Atoi: Atoi returns the result of ParseInt(s, 10, 0) converted to type int. strconv.ParseInt: ParseInt interprets a string s in the given base (2 to 36) and returns the corresponding value i. package main import ( "fmt" "strconv" ) func main() { str1 := "123" /** ...

不是所有数据类型都能转换的,例如string类型转换为int肯定会失败,编译就会报错cannot convert xxx (type string) to type int64; 低精度转换为高精度时是安全的,高精度的值转换为低精度时会丢失精度。上面的变量d与e就是这种情况; 要跨大类型转换,例如string与int的互转,可以使用strconv包提供的函数 ...

Atoi is equivalent to ParseInt(s, 10, 0), converted to type int. ParseInt interprets a string s in the given base (0, 2 to 36) and bit size (0 to 64) and returns the corresponding value i. How to Convert string to float type in Go? ParseFloat converts the string s to a ...
var apples int = 6 n := strconv.Itoa(apples) msg := "There are " + n + " apples" fmt.Println(msg) fmt.Printf("%T\n", apples) fmt.Printf("%T\n", n) } In the code example, we convert the number of apples into a string to build a message. Later, we output the type ...
