问题 Sorry for too long post, but I had no choise! So the question is “can we establish a blockchain (precisely DAG) as an infrastructure of a cryptocurrency, which uses only Proof Of Stack to securing transactions?”. What are the flaws of this approach? The scenario is like that: I develop and release the prototype software and run the first node. As a founder and the first member of the network, I made a to-do list of future develops of that software. The goal is improve software and strengthen

Calculate large decimals (more than 15 digits) in Javascript

由 陌路散爱 提交于 2019-12-04 06:10:07

For example: console.log(0.1 + 0.2) // 0.30000000000000004 And we know that we can avoid it using different libraries (for example I use bignumber.js), and now we have what expected: console.log(Number(new BigNumber(0.1).plus(0.2))); // 0.3 <script src="https://cdnjs.cloudflare.com/ajax/libs/bignumber.js/6.0.0/bignumber.min.js"></script> BUT Bignumber.js has limitations: It accepts a value of type number
