wei-caculate

Quick Start

npm i wei-caculate -S

Just export the function directly from the library and use it

const wei = valueToWei(1, 18)

consle.log(wei) // 1000000000000000000

Parameter Analysis

Since most project-based tools for blockchain calculations involve precision-related calculations, they all default to discarding the remainder all together after the exact bit, rather than rounding up
