There are a lot of problems here, the least of which is the leading0. A much bigger one is that thatBigInt'stoString()assigns a decimal-to denote negative rather than encoding it into the hex. As you may know, in binary formats (hex, base64, and binary - of course) negative number...
The last method we'll go over is theparseFloat()function that takes a string and converts it to a number with decimals (known as a point number). Here's what it looks like in code: Node.js Copy parseFloat("25")// returns 25 (typeof === number) Just like the previous two exampl...
This has landed innode.jsand Chrome, and it's documented on MDN, so Firefox support shouldn't be too far behind. However, it's not documented very well - not even the basic features that already exist or for non-big numbers - like converting Hex to Decimal and back again. Convert Big...

Moment.js will accept decimal values and do its best to handle them by rounding to the nearest whole number. As of2.12.0decimal day and month values use absolute value/round to convert to integers. This means that 1.5 rounds to 2, and -1.5 rounds to -2. ...
