import {subFees, subTax, subListing, listingFee, tax} from 'gw2e-tradingpost-fees'
// Subtract both the 5% listing fee and the 10% tax
subFees(100000)
// -> 85000
// Subtract the 10% tax
subTax(100000)
// -> 90000
// Subtract the 5% listing fee
subListing(100000)
// -> 95000
// Get the 10% tax
tax(100000)
// -> 10000
// Get the 5% listing fee
listingFee(100000)
// -> 5000But why not just
price * 0.85?
Because that's not how it works ingame. It is missing that there is a minimum of 1 copper for the listing fee, tax, as well as propper rounding. Yes, that makes a difference for cheap items.
