Numeric

A wrapper of Decimal.js

Usage

See the source code for more details.

All functions are same as Decimal.js and can convert from:

• String
• Number
• BigInt
• Array of Number
• bn.js
• BigInteger.js
• Big Numbers
• Decimal.js

Examples:

import { Numeric } from '@agrozyme/numeric';
const test1 = new Numeric('1');
const test2 = new Numeric(2);
const test3 = new Numeric(3n);
const test4 = new Numeric([4]);
const test5 = new Numeric(new BN(5));
const test6 = new Numeric(bigInt('6'));
const test7 = new Numeric(BigNumber.from(7));
const test8 = new Numeric(new Decimal(8));

Constants

Same as Etehreum Constants bignumber constants but export to Numeric type

• NegativeOne
• Zero
• One
• Two
• WeiPerEther
• MaxUint256
• MaxInt256
• MinInt256

Helper Functions

• tryParse: try parse value to Numeric

const test = tryParse('test');
//  test is false

• isRange: test value range

const test = isRange(0, -10n, '10');

• isInteger: test value is a integer

const test = isInteger('0.1');

• isUnsignedIntegerBits: test value is a unsigned integer that has significant bits
• isSignedIntegerBits: test value is a signed integer that has significant bits

const test1 = isUnsignedIntegerBits(8n, '256');
const test2 = isSignedIntegerBits(8n, '256');

• createArrayCompareFunction: create a simple array compare function

const ascending = createArrayCompareFunction(true);
const descending = createArrayCompareFunction(false);

Format Functions

• formatValue: use format-number to format a Numeric-Like value

const text = formatValue(1000, { prefix: '$' });

Convert Functions

All convert functions are accept one Numeric-Like argument, except toNumerics

• toNumerics: convert a Numeric-Like array to a Numeric array

import { toNumerics } from '@agrozyme/numeric';
const test = toNumerics(['1', 2, 3n]);

• toNumeric: convert a Numeric-Like value to a Numeric value
• toIntegerString: convert a Numeric-Like value to a interger string
• toBigInt: convert a Numeric-Like value to a native bigint value
• toBN: convert a Numeric-Like value to a BN value
• toBigInteger: convert a Numeric-Like value to a BigInteger value
• toBigNumber: convert a Numeric-Like value to a BigNumber value

Config Functions

• getNumericConfig: get NumericConfig that same as Decimal.Config
• setupNumericConfig: setup NumericConfig
