> This suited me down to the ground because I pointed out to everybody that Javascript couldn't be guaranteed to treat numbers and calculations in a way that would keep the regulators auditors happy,
Javascript can represent dollar values up to $2.25 billion at a resolution of ten-thousandths of a cent without any loss of precision.
I would want all money calculations done by the backend team as a matter of policy. But it's not a technical limitation.
While you are correct that it can _represent_ these numbers with that precision... it cannot operate on them and retain that precision, so DO NOT USE FLOATS TO REPRESENT MONEY. Thank you for your time.
let a = 35
let b = -34.99
console.log(a+b)
// output: 0.00999999999999801
