Hex Package
The Flux Hex Package provides functions that perform hexadecimal conversion of int
, uint
or bytes
values to/from string
values.
hex.string
The hex.string()
function converts a single value to a string. It is like a standard string() function, but it encodes int
, uint
and bytes
to hexadecimal lowercase characters.
Example:
import "contrib/bonitoo-io/hex"
a = hex.string(v: 12)
// a is "c"
b = hex.string(v: bytes(v: "hi"))
// b is "6869"
hex.int
The hex.int()
function converts a hexadecimal string representation of a number value to an integer.
An input value can be optionally prefixed by 0x
.
Example:
import "contrib/bonitoo-io/hex"
a = hex.int(v: "c")
// a is 12
b = hex.int(v: "-d")
// b is -13
c = hex.int(v: "0xe")
// c is 14
c = hex.int(v: "-0xF")
// d is -15
hex.uint
The hex.uint()
function converts a hexadecimal string representation of a number to an unsigned integer.
An input value can be optionally prefixed by 0x
.
Example:
import "contrib/bonitoo-io/hex"
a = hex.uint(v: "C")
// a is uint(12)
b = hex.int(v: "0xd")
// b is uint(13)
hex.bytes
The hex.bytes()
function decodes a string of hexadecimal characters into a flux bytes value.
Example:
import "contrib/bonitoo-io/hex"
a = hex.bytes(v: "6869")
// a is bytes("hi")
