Functions

func B64ToNum

func B64ToNum[N constraints.Integer | constraints.Float](str string) N

B64ToNum Base64 转换成数值.

Example

package main

import (
	"fmt"

	"github.com/xuender/kit/types"
)

func main() {
	fmt.Println(types.B64ToNum[int]("D"))
	fmt.Println(types.B64ToNum[int]("A"))
	fmt.Println(types.B64ToNum[int]("-lQL5AA"))
	fmt.Println(types.B64ToNum[int]("WU4!fR9v4"))

}

Output:

3
0
-40000000000
6284325805349880

func Bytes2Number

func FormatFloat

func FormatFloat[T constraints.Float | constraints.Integer](num T, prec int) string

FormatFloat 浮点数格式化成字符串.

func FormatUint

func FormatUint[T constraints.Unsigned](num T) string

Example

package main

import (
	"fmt"

	"github.com/xuender/kit/types"
)

func main() {
