您好，我自己在window上装的ruby，但是我写的公式：require_relative 'quad_tile'
# 支持命令行输入整数经纬度和 zoom，自动转为度
print '请输入纬度 (整数): '
lat_int = gets.strip.to_i
print '请输入经度 (整数): '
lon_int = gets.strip.to_i
print '请输入缩放级别 (zoom): '
zoom = gets.strip.to_i
lat = lat_int / 10_000_000.0
lon = lon_int / 10_000_000.0
tile_id = QuadTile.tile_for_point(lat, lon, zoom)
puts "tile_id: #{tile_id}"
# 反查中心经纬度
center = QuadTile.tile_center_latlon(tile_id, zoom)
puts "tile center lat/lon: #{center.inspect}"
结果算出来的结果是这样的：
C:\Users\Administrator\Desktop\test\lib>ruby quad_tile_test.rb
请输入纬度 (整数): 351704956
请输入经度 (整数): 1130668539
请输入缩放级别 (zoom): 17
tile_id: 6795010254
tile center lat/lon: [35.170440629756364, 113.06716918945312]
