Crypto Token Calculator

To be used on screens or APIs in which the user can choose the quantity or percentage of tokens to purchase. These functions receive the token configuration as minimum value for purchase, minimum value of each installment, and it returns the percentage purchased, the cost and how many tokens this will result in. It does not depend on the currency used as you must send it in the currency you are working in.

Functions

All the functions returns CalcResultInterface that has:

CalcResultInterface

desirePercent: (number) Percent between 0 and 1, that means a desired percentage for total amount of tokens available

coust: (number) Value of this operation. Remember, all values are based on the same currency.

tokens: (number) Amount of tokens resulting from this operation

TokenInfoInterface

minValue: (number) Minimum value in currency allowed to buy this token

availableTokens: (number) Total quantity of current available tokens

valuePerToken: (number) Coust per 1 unit of this token in currency

slotUnitValue: (number) Group amount of token values that are allowed to purchase, for example, if slotUnitValue is 5, you can only purchase using multiples of 5 coins to purchase this token.

calcTokenPercent

Receives tokenInfo and the desired percentage (desirePercent) of tokens and returns CalcResultInterface.

Ideal if you are using a bar to symbolize the percentage of tokens desired for purchase.

Or you need to check whether the value sent corresponds to an accepted value.

Usage

import { TokenInfoInterface, calcTokenPercent } from "crypto-token-calculator";

const token: TokenInfoInterface = {
  minValue: 100,
  availableTokens: 1000000,
  slotUnitValue: 100,
  valuePerToken: 1,
};

const percentDesired:Number = 0.5000001;
const result = calcTokenPercent(token, percentDesired);

console.log(result);

//output: { desirePercent: 0.5001, coust: 500100, tokens: 500100 }

calcTokenValue

Receives tokenInfo and the total value (desiredValue) of tokens and returns CalcResultInterface.

Ideal if you are using a bar to symbolize the percentage of tokens desired for purchase.

Or you need to check whether the value sent corresponds to an accepted value.

Usage

import { TokenInfoInterface, calcTokenValue } from "crypto-token-calculator";

const token: TokenInfoInterface = {
  minValue: 100,
  availableTokens: 1000000,
  slotUnitValue: 100,
  valuePerToken: 1,
};

const desiredValueToBuy: number = 5000;
const result = calcTokenValue(token, desiredValueToBuy);

console.log(result);

//output: { desirePercent: 0.005, coust: 5000, tokens: 5000 }
