[BUG] When the zoom level is set in `baseMap`, it is automatically converted to an integer.

[YongGoose]

Description

If you set minZoom or 'maxZoom' to a float value like 2.5, it will automatically be converted to 2.

{
  minzoom: 2.5,
  maxzoom: 20,
  sql:
    "SELECT id, tags, geom " +
    "FROM osm_boundary " +
    "WHERE tags ->> 'admin_level' = '2' " +
    "AND tags ->> 'maritime' = 'yes';",
}

Environment

• Browser/Version: chrome
• Version: 0.8.1

Expected vs Actual Behavior

• Expected: Setting minZoom to 2.5 should apply it when the zoom level is 2.5 or higher.
• Actual: However, it actually applies when minZoom is 2.0 or higher.

Attachments (Optional)

Maritime boundaries should be applied from zoom level 2.5 and above, but they can be seen applying from 2.0.
