Utility methods to convert to and from number values
- numberFromBuffer Creates a Number value from a Buffer object.
- numberFromHex Creates a Number value from a Buffer object.
- numberToBuffer Creates a Buffer object from a number.
- numberToHex Creates a hex value from a number.
numberFromBuffer
Creates a Number value from a Buffer object. (alias of bufferToNumber)
numberFromBuffer (value?: Buffer): number
numberFromHex
Creates a Number value from a Buffer object. (alias of hexToNumber)
numberFromHex (value?: Hex): number
numberToBuffer
Creates a Buffer object from a number.
numberToBuffer (value?: number): Buffer
null/undefined/NaN inputs returns an empty Buffer result. number input values return the actual bytes value converted to a Buffer.
import { numberToBuffer } from '@polkadot/util';
const buffer = numberToBuffer(0x1234); // => Buffer.from([0x12, 0x34])
numberToHex
Creates a hex value from a number.
numberToHex (value?: number): string
null/undefined/NaN inputs returns an empty 0x result. number input values return the actual bytes value converted to a hex.
import { numberToHex } from '@polkadot/util';
const hex = numberToHex(0x1234); // => '0x1234'
