Adjust the db in audio bus without using the slider

Godot Version

Question

silly question but cant find answer anywhere.
Is there another way to change the db for a audio bus without using the slider next to it which is this thingy:

since I just cant get the db effect that I want by sliding, its always off by 0.1 or sth.
Is there a way to input db for the bus like what adobe premiere does?

Try this:

var bus_idx = 0
var volume_db = 0.5
AudioServer.set_bus_volume_db(bus_idx, volume_db)
