GO 数字运算
大整数运算
// bigint project main.go package main import ( "fmt" "math" "math/big" ) func main() { // Here are some calculations with bigInts: im := big.NewInt(math.MaxInt64) in := im io := big.NewInt(1956) ip := big.NewInt(1) ip.Mul(im, in).Add(ip, im).Div(ip, io) fmt.Printf("Big Int: %v\n", ip) iq := big.NewInt(10000) ip.Mod(ip, iq) fmt.Printf("Big Int: %v\n", ip) }
大整数比较
enough := bigWeiBalance.Cmp(bigWeiValue)
原来,big.Int 类自带cmp方法
返回 1:前面的big.Int 实例大于cmp方法big.Int 参数
返回 0:前面的big.Int 实例等于cmp方法big.Int 参数
