Functions

func IsNumber

func IsNumber(input any) bool

func ToAddress

func ToAddress(input any) common.Address

Convert string into go-ethereum address.

Input must be go-ethereum address or length 42 string, otherwise will return 0x0.

Example

fmt.Println(ToAddress(1))
fmt.Println(ToAddress("111"))
fmt.Println(ToAddress("0xdAC17F958D2ee523a2206206994597C13D831ec7"))
fmt.Println(ToAddress("0xdac17f958d2ee523a2206206994597c13d831ec7"))

Output:

0x0000000000000000000000000000000000000000
0x0000000000000000000000000000000000000000
0xdAC17F958D2ee523a2206206994597C13D831ec7
0xdAC17F958D2ee523a2206206994597C13D831ec7

func ToBigInt

func ToBigInt(input any) *big.Int

Convert number or string into *big.Int.

Input must be number or number string, otherwise will return 0.

Example

fmt.Println(ToBigInt(1))
fmt.Println(ToBigInt(1.4))
fmt.Println(ToBigInt(1.8))
fmt.Println(ToBigInt("2"))
fmt.Println(ToBigInt("2.3"))

Output:

1
1
2
2
<nil>

func ToBool

func ToBool(input any) bool

Convert anything to boolean.

func ToDecimal

func ToDecimal(input any) decimal.Decimal

Convert number or string into decimal.Decimal.

Input must be number or number string, otherwise will return 0.

Example

fmt.Println(ToDecimal(big.NewInt(9)))
fmt.Println(ToDecimal(9.9))
fmt.Println(ToDecimal("9.99"))

Output:

9
9.9
9.99

func ToFloat64

func ToFloat64(input any) float64

Convert number or string into float64.

Input must be number or number string, otherwise will return 0.

Example

fmt.Println(ToFloat64(1))
fmt.Println(ToFloat64(1.4))
fmt.Println(big.NewFloat(1.8))

Output:

1
1.4
1.8

func ToHash

func ToHash(input any) common_eth.Hash

Convert anything to hash.

func ToInt

func ToInt(input any) int

Convert number, string or bool value into int64, and then convert into int.

func ToInt64

func ToInt64(input any) int64

Convert number, string or bool value into int64.

Input must be number, number string or bool value, otherwise will return 0.

Float number will return the round int.

Can convert strings start by 0x, 0o or 0b to Dec int.

True ==> 1; False ==> 0.

Example

fmt.Println(ToInt64(1.4))
fmt.Println(ToInt64(1.8))
fmt.Println(ToInt64(big.NewInt(2)))
fmt.Println(ToInt64(big.NewFloat(2.6)))
fmt.Println(ToInt64("0x11"))
fmt.Println(ToInt64("0o66"))
fmt.Println(ToInt64(true))

Output:

1
2
2
3
17
54
1

func ToLowerString

func ToLowerString(input any) string

func ToString

func ToString(input any) string

Convert anything to string.

Example

fmt.Println(ToString(1))
fmt.Println(ToString(1.1))
fmt.Println(ToString(true))

Output:

1
1.1
true

func ToUpperString

func ToUpperString(input any) string
