Float slider fails if initial value is integer

[backspaces]

Using release 0.5.1, I initially posted this as a comment for issue #48 but decided it should be its own issue.

Issue: Float slider (step is float) fails to display float value if initial value is integer, even tho the onChange shows the correct value. It is a display problem

This (es6, babel):
var gui = new dat.GUI()
var callback = (val) => console.log('message', val, UI)
var UI = {speed: 0}
gui.add(UI, 'speed').min(-10).max(10).step(.5).onChange(callback)
.. the console shows the .5 steps but the dat.gui display only shows integer values.

This workaround shows the correct float steps, appearing to be initialized as the 0 int value:
var UI = {speed: .5}
gui.add(UI, 'speed').min(-10).max(10).step(.5).listen().onChange(callback)
UI.speed = 0

Prior comment:
This did not completely fix it for me. If I have a float slider that starts out with an integer value, I still get this problem. Works fine if the initial value is non-integer.

Does the fix here work for everyone else? I.e. float slider that starts out with integer initial value?

I did find a work-around:

Make sure the initial value is non-integer.
Add .listen() to the property.
Then set the property to the integer value.
I.e. I start with:
var UI = {
...
x: .1, // workaround for float slider bug
y: .1,
z: .1,
...
}
gui.add(UI, 'x').min(-10).max(10).step(.1).listen().onChange(callback)
gui.add(UI, 'y').min(-10).max(10).step(.1).listen().onChange(callback)
gui.add(UI, 'z').min(-10).max(10).step(.1).listen().onChange(callback)
UI.x = UI.y = UI.z = 0

@backspaces thanks for workaround (setting to non-integer). I wish they had .precision(.01) method.

Fixed by pull request #47 (if you use step). Not sure when if it will be merged
