any是interface{}的别名,表示空接口,可以存储任何类型的值。 2. 编写代码示例,展示如何将interface{}类型转换为int类型 我们需要使用类型断言来检查any类型变量背后的具体类型,并进行相应的转换。以下是一个完整的代码示例: go package main import ( "fmt" ) func convertToInt(v any) (int, e
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" /** ...
// ToAnyE converts one type to another and returns an error if occurred. func ToAnyE[T any](a any) (T, error) { var t T switch any(t).(type) { case bool: v, err := ToBoolE(a) if err != nil { return t, err } t = any(v).(T) case int: v, err := ToIntE(a...

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 ...
1. Int to hex conversion using fmt.Sprintf()In Golang (other languages also), hexadecimal is an integral literal, we can convert hex to int by representing the int in hex (as string representation) using fmt.Sprintf() and %x or %X. %x prints the hexadecimal characters in lowercase and ...
