Block reward and supply calculation

supply.js

for (block_height = 0; block_height < 6_930_000; block_height += 210_000) {
  
  epoch = Math.floor(block_height / 210_000) + 1
  
  coin = 100_000_000
  reward = Math.floor(100 * coin / Math.pow(2, epoch))
  
  supply = 0
  for (i = 1; i <= epoch; i++) {
    supply += Math.floor(100 * coin / Math.pow(2, i)) * 210_000
  }
  
  // Or 21_000_000
  percent = (supply / coin / 20_999_999.9769) * 100 
  
  console.log(`${epoch}  ${(reward / coin).toFixed(8)}  ${(supply / coin).toFixed(8)}  ${percent}`)
